The VCE Journey Journal / Re: Weekly Journal
« Last post by Autime on 1 hour ago »
False Foundation

I’m finally updating this journal again, well I only missed one week so maybe that’s an exaggeration, but it feels like a long time. I wish I could say that I’ve caught up with what I hoped to and that I’m on track to do well with the goals I’ve set, but I’m not.

I think that the reason I’ve been so unproductive is because I set my expectations too high, I subconsciously make studying out to be a much harder task than it really is. I think this is so I have an excuse as to why I’m not doing as well as I’d like, when the task I must complete is so challenging it prevents me from seeing my true abilities since I don’t use my time well or leave it to the last minute. I don’t think my problem is that I set the bar too high for myself, it’s instead that I don’t want to jump to see if I can reach it but also believe that it will likely not be enough if I lower it into a level I’m comfortable with, so the cycle continues. It’s kind of like Schrödinger's cat, in the time before an action you don’t know your potential, in a sense you are limitless for that time since you could enough or you may not be, I don’t want to know the answer when it’s uncertain.

So, I’ll rebuild my expectations from the ground up. It’s better to do something than nothing for now. I’m only going to tell myself to write a single word of an essay if I need to and only do half a problem of a maths question if necessary, then I’ll work my way up by increasing the amount based on my own intuition and what I think I can do consistently. This way, I won’t be hesitant or resistant to starting since it’s certain that I’ll be able to reach my goal. Hopefully this is a better approach than what I’ve been doing so far, only studying when I believe I can reach an unreasonably high standard. I think with that kind of method, it leads to burnout and inconsistency since it’s easier to doubt your abilities as it’s an expectation build off of baseless confidence in the first place.

Last week I completed an English SAC which I didn’t prepare enough for, I doubt I’ll do well. I also have to learn all of probability for methods since I didn’t pay enough attention in class and did next to no textbook questions. There’s also about a chapter of specialist work to do and some physics exercises to work on. Not to mention the practice exams and holiday homework I received. However, I believe that if I can start with a smaller workload and work my way up I’ll be able to do it. Thinking back, that was how I was able to accomplish similar results, by decreasing my expectations initially to get started. I’ll need to remember to repeat this process whenever I see myself getting off track so I can keep on building momentum consistently.

I know a lot of this entry is not really directly related to VCE schoolwork, but writing this here helps me to face things that prevent me from studying or doing anything productive and come up with potential solutions that might someone else.

T4 Holidays Week 1 Goals:
- Do my best to catch up, get started on everything (set more defined/measurable goals once I see what I’m capable of doing now)

Site Discussion / Is Engineering A Good Subject Choince?
« Last post by Tech1234 on 1 hour ago »
I am about to go to grade 11.
I am definetly already doing Methods, Specalist, Chemistry, Physics & English.
I perform well with all subjects excluding english.
I am planning to go into medicine therefore am planning to have 5 high atar subjects other than english to go towards atar.
I have selected engineering as my 5th subject, however I have not seen many students at all pick this subject, especially not any students who went for medicine.
So, my I am wondering, is engineering actually as high atar subject? and why don't many people pick it?

VCE Biology / Can I get a 40 ss?
« Last post by shahifa on 5 hours ago »
Hi guys

I’m wondering if I can achieve a study score of 40 for biology with these current sac marks - my cohort is relatively strong with our averages sitting above 70 and my biology teacher is a VCAA examiner herself so I’d say the SACs she makes for us are on the difficult spectrum.

1. 93 % - rank 3
2. 73 % - I wasn’t told my rank for this
3. 95 % - rank 6
4. 78 % - rank 6
5. 83 % - haven’t been told my rank for this

But I was told my average for all my sacs combined places me in position 6-7.
I’m aiming for a high mark in the exam preferably 80% or more.

So with that said, do I have a shot for a 40 ss?

Hi, is time considered a discrete or continuous variable?

It depends upon how the data is recorded. If the values are recorded with infinitesimal precision (ie. with infinitely long decimals like 1.4142135...) then it is a continuous variable. If the values are recorded in discrete chunks (ie. to the nearest hour or to the nearest day), then it is a discrete variable. On VCAA exams, the way in which the data is recorded is included in the question.

Can someone help me with what a "three-median line" is and how this is different to median smoothing? There was a question about 3-median line in the vcaa 2011 exam but I'm not sure if it's still relevant to the current study design. Thanks

It's a linear regression method (ie. trying to achieve a similar sort of thing to the least-squares regression method that you'll be more familiar with) using the median of three equal chunks of data. It is not a technique used to smooth each data point. It is no longer part of the study design.

Compare the ways in which The Queen and Ransom convey the importance of humility and humanity

Set in times rocked by crisis, David Malouf’s novel Ransom and Steven Frears’ film The Queen celebrate those who show humanity in their responses and interactions. The creators dictate the importance of humility on ones’ external identity, as characters representative of the ‘common man’ serve as physical embodiments of modesty. The texts also convey the importance of humanity through providing a glimpse into the intimate spheres of legendary sovereigns, endorsing their journeys as they connect with their own humanity. The film and novel depict the value that is to be found in civil interaction, portraying the benefits of treating one another's adversaries with humanity.

The common man is celebrated in both mediums for his innate humility. In Malouf’s text, Somax is representative of the ordinary soul, as his very figure emanates modesty. Malouf conveys his simplicity through his clothes, as he wears a “homespun robe and broken sandals”. Indeed, his self-image reflects his outward modesty, as he constantly refers to himself as a “lowly carter”. Malouf celebrates the carter’s modesty through the respect he gained from Priam, as the king “finds so much honest goodwill in the man”, he “begins to look at him with growing respect”. In this way, Malouf indicates that humility of spirit garners genuine respect. In a like manner, Frears also celebrates Tony Blair for his modesty. Providing insight into his home life, Frears imagines the prime minister's humble home with contemporary furnishings. Blair, walking around his house, dons a football jersey. Frears suggests, that in his modesty, Blair is better able to appreciate and represent the culture of the modern population. Freeze indicates the importance of this humility on Blair, as he is thus better able to connect with his people and is celebrated as “the only person who seems to have read the situation correctly”. Frears does, however present Blair’s humility as a deliberate image. As a politician representing the ‘modernizer’ ideology, his humble image is, to an extent, calculated to capture his political identity. Indeed, the omnipresence of the media reinforces this view. Blair is hailed in the media narrative as “the man of the moment”. Thus, in this respect, Frears endorses leaders who are able to project a humble image in the social sphere. In a different vein, Malouf's characterization of Somax’ integrity is purely genuine. His repetitive habit of “rubbing his nose” is a gesture that serves to comfort him but also those around him in its unpretentiousness. Malouf highlights how Somax’ basic manner is genuine, and a man who has “never had to do with any bit simple folk like himself”, the image of modesty he exudes comes not to gain a political foothold but is rather as he is. His “lack of knowledge of the forms” projects his inexperience in the sphere of power, as he is pure of all of the affectations that accompany influence. As such, Malouf celebrates the carter instead for the authenticity of his humility. Thus, the creators depict the value of integrity as it manifests in the outward view, celebrating the 'common man' for his intrinsic modesty.

Leaders in both texts, while depicted as human on the inside, must take spiritual journeys before realising the importance of maintaining humility in a position of power. In his introspective narrative style, Malouf divulges Priam's inner humanity, exposing the “real man inside so much empty shining” that is hidden to the outer view. It is only when he embarks on a journey, however, that this humanity is exhibited in his actions. In his river crossing, Malouf suggests that a leader must step out of their “royal sphere”, and expose

themselves to the natural world if they are to understand the “small pleasures” that are to be found in being simply human. Malouf, then, celebrates the price, or' ransom' of royal pride that Priam trades for a more modest life experience. Frears, too, provides insight into the Queen's inner humanity. The film permeates into the Queen's intimate sphere, as she is shown in a pink robe behind the walls of her palace. Such a personal image conveys the Queen’s human vulnerability that is kept hidden from the outer view. Like Malouf, Frears also suggests that a leader must take a journey to recognise the importance of incorporating modesty in their royal image. As she crosses the stream, she must call for help, and is forced to reject the instilled sense of her regal infallibility to ask for aid. In conjunction with this, Frears’ zoom-out shot exaggerates the Queen's small figure against the scrolling landscape. In this way, Frears visualises Elizabeth as any human, conveying her change in accepting her human faults. Frears, then, explores the importance of this journey in the Queen’s coming to terms with the need to relinquish some of her pride. In Ransom, however, Priam’s journey culminates in success, as he reaches that Achaean camp. As it was his own desire to go “as a man... with nothing to with nothing but a simple cut”, Malouf rewards the king's efforts with his “triumph”. In this way, the king is celebrated for his pursuit of his humanity. By contrast, the Queen's river crossing is not successful, as her car breaks down in the stream. The car itself is the old model of a Jeep, symbolising the Queen's refusal to change. Through this journey, Frears condemns the problems that arise when one ignores the need to alter tradition. Thus, through the narrative device of a river crossing journey, Malouf and Frears explicate the importance of foregoing one’s entrenched pride in navigating unprecedented circumstances.

The resolutions of the text and film are brought about as leaders break cycles of hatred and forgo revenge. The deal between Priam and Achilles is ground-breaking, and the two leaders are able to overcome the division of the war and forge a new understanding “as one poor soul to another”. As the great hero Achilles “falls to his knees” to the king he has shamed, just as Priam had planned to do at the feet of the warrior, Malouf explicates the humility of both men, who are willing to reject their pride in reverence to one another. As their deal is successfully executed, Priam proclaims himself “a man remade” and Achilles feels a “lightness that is both new and a return”. Malouf celebrates the spiritual benefits of both leaders’ ability to cooperate with one another. Frears conveys a similar message, as the Queen “bend(s) a knee to Blair”, and Frears celebrates the benefits this brings her, as she is able to recover the love of her people. As she expresses “great humility” by joining her people in front of the palace gates, she receives a bouquet of flowers as the crowd begin to bow. Frears visualises the reconciliation between the Queen and the people, as the flowers are symbolic of the public’s admiration, and the people began to fall into gestures of reverence. The Queen's own gesture, however, is revealed to be ingenuine as Elizabeth reveals she feels she did not “have a choice”. The motif of press agents also works to convey the inauthenticity of her statement, as it is not her who writes the words that touch the nation. Nevertheless, Frears celebrates her humility in her acquiescence to a response that, while not being reflective of her inner feelings, supports the public emotion. In Malouf's text, the affinity between Achilles and Priam is much more profound, as they share “a kind of intimacy” in their connection as fathers. Malouf endorses instead the leaders’ genuine connection on a human level. At a comparative glance, then, the texts divulge the necessity for leaders to display their outer humanity leaders to recover what they have lost.

The Queen and Ransom divulge the power to be found in ones’ own humanity, and how individuals with the humility to connect with others through their emotions are better able to navigate crises. The texts consider the path that must be taken to access one's own humanity, celebrating those who represent modesty, and lead others to engage with their own. The creators, then, endorse leaders as they “learn a little of what (human experience) might be, and what it is to bear it as others do”, imparting the importance of understanding the sentiment of ones’ people on true leadership.

VCE Chemistry / Re: VCE Chemistry Question Thread
« Last post by miyukiaura on 9 hours ago »
Hey guys,

I just had a question about determining the calibration factor by electrical calibration.
For a temperature-time graph (attached), how do you know if the calorimeter is well-insulated or poorly-insulated, and whether to extrapolate back to when the current was turned on, or to simply read off the graph to determine the change in temperature? I know that for poorly-insulated calorimeters, the graph should decrease and be less linear, however, if it isn't as obvious, how would you know which method to use?

Thanks so much.

VCE Chemistry / Re: VCE Chemistry Question Thread
« Last post by wingdings2791 on 12 hours ago »
Hey everyone, just had a quick one about some titration theory.
"A student conducts an experiment to determine the ethanoic acid concentration in a commercial
brand of vinegar. An outline of her procedure and her measurements are provided below.
230.0 mL deionised water added to a 250 mL volumetric flask
20.0 mL of vinegar added to the flask
20.00 mL aliquots added to flasks and titrated against 0.150 M NaOH."

The solutions said that an error in this experimental design was that "20 mL added to 230 mL of water will not necessarily give 250 mL. Some liquids are miscible in each other. All concentration calculations will be subsequently affected," and suggested that "It should be made up to the mark and not have 20 mL added to 230 mL."

Would miscibility not result in an error regardless if we're filling the volumetric flask up to the mark or adding 20 to 230? Cheers

Hi saransh,
I think the main error described here is that the vinegar to the volumetric flask before the deionised water.

The analyte (vinegar) should always be added first to ensure that the correct concentration is achieved. When deionised water is added directly to the vinegar already in the flask, up to the \(250 mL\) mark, you know that the volume totals as close to \(250 mL\) as possible, and that the \(n(vinegar)\) is as close to \(20 mL\) as possible.

If the deionised water is added to the volumetric flask first, then the separately measured \(20 mL\) of vinegar is added to the deionised water, you risk decreasing accuracy. As the uncertainty of the volumetric flask and the pipette used to measure the vinegar might result in inaccurate measurements, separately measuring the deionised water and vinegar and then adding them together combines the potential for error from two pieces of equipment. That is: when vinegar is added first, although inaccuracy can still come from the uncertainty of the \(n(vinegar)\) measurement, the total \(v\) wouldn't be affected as much.
If the deionised water is added first, both the vinegar and water would be more likely to be measured inaccurately, compounding the error. I'll list the possible errors from measurement in each case here:

Water after vinegar
High vinegar: less water added to achieve \(v=250 mL\), inaccurately high \([CH_3COOH]\)
Low vinegar: more water added to acheive \(v=250 mL\), inaccurately low \([CH_3COOH]\)

Vinegar after water
Low water/low vinegar: \(v<250 mL\), inaccurately low \([CH_3COOH]\) calculated as \(v=250 mL\) will be used
Low water/high vinegar: \(v(solution)\approx\ 250 mL\), aliquots have higher \([CH_3COOH]\), high \([CH_3COOH]\) calculated
High water/low vinegar: \(v(solution)\approx\ 250 mL\), aliquots have lower \([CH_3COOH]\), low \([CH_3COOH]\) calculated
High water/high vinegar: \(v>250 mL\), high \([CH_3COOH]\) calculated as \(v=250 mL\) will be used
High water/accurate vinegar: low \([CH_3COOH]\) from \(v>250 mL\) and aliquot \([CH_3COOH]<\) actual
Low water/accurate vinegar: high \([CH_3COOH]\) from \(v<250 mL\) and aliquot \([CH_3COOH]>\) actual
Accurate water/high vinegar: high \([CH_3COOH]\) from \(v>250 mL\) and aliquot \([CH_3COOH]>\) actual
Accurate water/low vinegar: low \([CH_3COOH]\) from \(v<250mL\) and aliquot \([CH_3COOH]<\) actual

As you can see, measuring the deionised water and vinegar separately, then adding the water first creates many more potential errors than adding the vinegar first and topping up the volume with water accordingly. This makes vinegar first, water second a more accurate approach.

Other errors
I don't see an error that would result from the miscibility of liquids. If anything, I would've thought that the analyte and titrant being immiscible would pose a problem, as this suggests that they would not react with each other and sit in the conical flask as a heterogenous solution.

Some other errors you could discuss, in case you need more ideas:
- No mention of equipment rinsing or swirling the solution to dissolve particles
- Indicator is not added to the analyte prior to titration
- The phrasing used is 'aliquots added to flasks and titrated against \(0.150M NaOH\)', which falsely implies that this is a back titration
- No mention of the titration process beyond 'titrate vinegar': should specify that three concordant titres must be achieved/results must be recorded (precision)

Anyways, that's what I think is going on in this question; it does seem a little strange. Hope I could help, let me know if there are any errors (see what I did there) :)

GAT (General Achievement Test) / Re: GAT Writing Task 2
« Last post by lastapasta on 14 hours ago »
hi, i got a 50 in the writing component of the GAT last year

i personally choose to do persuasive, but not with the strict conventions. i put some anecdotes in, and i addressed all 4 prompts given. i was also told that the persuasive approach would be better, but i think adding some creative flair pays off well. hope this helped!
