2020 Biology Exam

[homeworkisapotato]

Hey everyone! How's everyone feeling about the Bio exam in 6 days?

[Himalia1975]

I was really stressed out 20 days ago, I haven't managed to do what I planned to do this past couple of days but for some reason, I am not stressed for this exam. Maybe because I have a cushion to fall back on since I'm in year 11 and I can save myself next year if all doesn't go to plan.

How did everyone find the 5 mark question?!

[Adam_🎓🧾]

I finished kinda early... Hope I didn't completely miss any of the questions...or my 40 goes down the drain haha

Did anyone else think that the Bio exam was suspiciously easy? I'm a bit worried that I found it so easy... it was easier than my past practice exams.

I found it as easy as past exams....almost makes me think I missed a difficult question or something haha

How did everyone find the 5 mark question?!

i wrote ltiereally everything i could think of but i dont know if i got all the marks lol so unexpected. i wrote stuff like where the restriciton sequence was, how many restriction sites, how many strands produced) and the sizes of them

What did everyone think about the multi choice qs asking about B and T cell memory?

I did find it very easy and the fact that everyone else did worried me as well! However you have to write very specific things which I think 50% of people would miss. It’s not about the write answer it’s about what VCAA wants- that’s the sad thing about VCE you can be basically right but it needs to be RIGHT.

Do you think I will lose a mark for accidentally writing ethium bromide rather than ethiduim bromide?

Hmm, can never be certain but I think it could go either way for you. There isn't really anything that is actually called "ethium bromide" (that I could find) so your answer should be identifiable to your assessor as ethidium bromide.

Problems do occur is when you mispel something and it gives your answer a different meaning e.g. miosis vs meiosis

Teacher said that as long as they can understand it you'll get the necessary marks.

How did everyone find the 5 mark question?!

Hey there.
At first I wasn’t so sure about what this question was referring to. I basically broke down the sizes of different fragments that were produced by the use of different restriction enzymes. Then I wrote an ending statement saying that BamHI had only one recognition site on the DNA whilst HindIII had two… I think that’s along the lines of what was expected. The stem of the question stated that the student wanted to see the effect of different restriction enzymes on DNA, so that is essentially what I talked about.

I’m not entirely sure what kinds of things we were supposed to talk about… if anyone knows, please correct me if I’m wrong.

I wrote a bit about the different lengths and number of recognition sites, and drew a diagram showing them relative to each other and how many base pairs each fragment was. But I also talked about accuracy, precision and limitations. My teacher told me after that the question was probably just looking for a really detailed explanation of the restriction enzymes and none of the experimental design stuff.

Where did everyone put the H. denisovans on the phylogenic tree?

I think I might have screwed up big time because I put denisovans branching off heidelbergensis haha

Now that I think about it I feel like my answers weren't specific enough yikes
