Personally, I am not sure I have heard of test providers giving sample answers. Of course, the CFAI provides guideline answers to prior years’ actual exams. Keep in mind, these guideline answers are extensive and there is simply no way anyone could organize and write the same answer given the time constraint.
In my preparation for the morning session, I would always time myself. Not only does this give you a great gauge of how to allocate your most valuable resource (time) over the course of the morning section but it also guided me in formulating an “answer template”, if you will. I derived said template by doing the following:
Do an old exam and answer the question in a way that you perceive to be sufficient. Immediately after you are done, read through the guideline answer carefully. Make sure you understand how the CFAI derived the answer and the evidence in support of it. Compare your answer to the guideline answer. Did you come to the same conclusion, i.e. give the same answer? If so, you’re off to a great start. Now, understand that there is a lot of fluff in the guideline answer. HIghlight the sections of the guideline answer that a) clearly give an answer to the questions and b) support the answer with reasons/evidence. Those are the key pieces you need. After doing so, you can piece together your template answer in a concise and succint way. Simply pick the answer and place it at the top. As stated before, this should be one sentence. Next, pick however many reasons/examples the Institute asks for and organize them into bullet points below the answer.
To make this more tangible, let me provide an example. Let’s say the question gives you the background on an individual investor and asks you which asset allocation would be appropriate for said investor. Assuming you have four choices to choose among, I’d answer as follows:
Answer:
Choice A is the appopriate asset allocation for the investor given the information provided.
Support:
Bullet Point 1: Choice B is inappropriate as it does not meet the investor’s after-tax return requirements. Show calculation, if necessary.
Bullet Point 2: Choice C is inappopriate as it violates the investor’s risk objective. Show calculation, if necessary.
Bullet Point 3: Choice D is inappropriate as it lacks the same diversification benefits as Choice A. Provide evidence (i.e. 70% allocation to private equity).
If you want, provide a conclusion at the end of the answer stating that Choice A meets all of the return and risk objectives, and provides diversification benefits.
Anyway, that was my strategy. From what it looks like in my score matrix, it worked. Take it for what it is and realize that everyone has a different way of answering.
