Usually, the last question asks you to write a discussion, design an experiment, write an introduction or evaluate the results.
If it is a discussion, I followed a set formula which almost always guaranteed me at least a 7/10 - because to get full marks, it really comes down to specificity and your understanding of the context they give you.
So to write a discussion (remember, past tense!)
1. Hypothesis (population - IV - prediction - DV - IV)
e.g. It was hypothesised that school students who are taught using a four week positive reinforcement program will have a higher performance in mathematics compared to before the program than those who don't.
2a. "This hypothesis was supported as the results were statistically significant with a p-value of less than 0.05. This means that the probability the results occurred due to chance was less than 5% (less than the limit for statistical significance of 5%).
2b. "This hypothesis was rejected as the results were not statistically significant, with a p-value of more than 0.05. This means that the probability the results occurred due to chance was more than 5% (more than the limit for statistical significance of 5%)
3. "The results further show this, because..." (quote the data given, note any trends, compare between control and experimental group - be as specific as possible here)
4. "The implications behind this is that..." (use key terms from the relevant key concepts you learned in the course, such as operant conditioning, Loftus, etc.; then talk about the wider applications to real life)
e.g. The implications behind this is that, using principles of operant conditioning (a type of learning involving formation of an association between a response and its consequences), were used with positive reinforcement. This increases the likelihood of a behaviour occurring again by providing a pleasant outcome as a result of this behaviour. Therefore, in order to improve a school's mathematics performance on tests and exams, the school should have their teacher provide pleasant consequences (positive reinforcement) for correct math answers while teaching.
5. Weaknesses (aim for 3 weaknesses - e.g. if an independent groups design was used and the impact this has; pros and cons and how the cons overcame the pros in this experiment. Definitely talk about confounding variables and what effect they had - again, be SPECIFIC to this particular experiment)
6. Improvements (aim for 3 improvements - e.g. "a matched participants design should've been used because..." - specificity is key here as well)
For an introduction, it should include:
1. Short background of the key concepts related to the experiment
2. Aim
3. Research hypothesis (general)
4. Operationalised IV
5. Operationalised DV
For designing an experiment (the question stem itself should specify which parts it wants. Usually it wants a hypothesis and procedure)
1. Hypothesis
2. Materials (may or may not be necessary)
3. Ethics
4. Procedure. Mention sample size, description of the sample (same age, same size, etc.), which experimental design (e.g. independent groups, etc.), include a short definition of the design for insurance, experimental and control groups, controlled variables, how to collect data, repeat experiment. Always remember to be SPECIFIC (e.g. for how long will you expose the experimental group to the IV?)
For evaluation of results (generally)
1. Hypothesis and whether it's been supported/rejected
2. How did the results show this?
3. Explanation of the results using key concepts
4. If rejected, what should've been expected?
Aaand that's as far as I could remember. For the discussion bit, I looked through my notes from last year (can't remember in that much detail XD)
Hope that helped!

...Hmm I should include this in my Psych guide...
