The Kaplan mocks seem pricey to purchase online, however they seem to be good so trying but I want to know how Kaplan compares with Wiley in terms on their mock exams.
Kaplan is easier and more straightforward in my opinion.
I am studying with Kaplan, and I have finished both mock exam books (total of 12 60-question exams). I agree with 125mph, the exams were extremely easy. If you are already studying with Wiley (meaning you already have enough practice), I think its best just jump into the mock exams provided by CFAI to measure your understanding of the curriculum before buying Kaplan.
Wiley exams are very badly written and full of mistakes.
Schweser exams are easy.
