Sorry, didn't see your msg before.

Depends on your personal preferences - I used to do at least 60 questions in one set at the beginning, but then realized that this was very inefficient. I would get bored by the end and not work as concentrated. So then I started doing smaller sets of about 30-40 questions - and of course take some time to carefully review the answers. I guess you could do even smaller sets, but since you also need to get used to doing large sets of questions like in the exam I wouldn't go too small.

Later on in your preparation, you need to start taking the test exams provided by Schweser and the CFA and here I would recommend doing the full 3 hour set in one go. I am not sure whehter one needs to take a full exam (i.e. two 3 hour sets) in a day. I didn't and it certainly didn't do any harm. What's important that you learn to manage your time for a 3 hour set.

I hope this helps!
