mock exams difficult

Based on my experience, mocks are usually tougher, if you look at schweser’s practice exams, the technique and approach used is different. I usually leave CFAI’s mock last (after completing 5-6 other mocks).

Another benefit of doing that is, you will probably save many hours and lots of frustration to realise that it was actually an error in the mocks (there’s usually a bit of a delay in publishing errata).

However, don’t give up, the more you do the better you get.
