I failed band 5 last year, passed this year. Last year when I failed I started January 1st, and used K/S study materials. I scored well on all the practices from K/S, but failed the actual exam. This time around I started December 1, and worked strictly from the CFAI circ.
CFAI circ was a lot more to cover, but at least that way you see everything that could be on the exam. I did all the EOCs, the online topic tests, and the CFA mocks from this year and last. The other thing I did that I found helpful was to redo mock exams and topic tests. Don’t just memorize the answer, but how to solve the problem. Do it over and over until you know it cold. Then do a new mock, and repeat.
The is no magic bullet, but being band 8 means your on the cusp. A few more correct answers, and strong ethics showing and you’re on to level 3.
Last thing I’ll say, register for level 2 tomorrow. It took the focus off the fail, and made me think about next time.
Best of luck through the rest of the program… level 2 is a tough one..
