Take at least 10 mock exams. Take mocks from a variety of sources not just one. Include at least 1-2 CFA mocks in your mix but don’t go back too many years with CFA ones, as the curriculum changes every couple of years.
Read the core materials for GIPS, take a day and just do it. The easiest way to approach GIPS is to only focus on the requirements. Don’t focus on any recommendations. That will cut the materials down a lot.
You can break your mock study sessions into half days. I typically did either AM or PM during a day then studied notes the second part of the day, then studied the answers the second day plus notes again… Then the third day I would do the second half of the test etc. By breaking it up, I could do more mocks each week without burning out. I only took one full exam “in real time” and that was the Kaplan CBT one, I did it on a Saturday the week before my exam.
The more mock exams the better, and focus hard on why you get questions wrong. That part of your learning is the key.
Cheers - good luck - you got this👍
