My suggestion:
use third party resources for your reading(read at least twice)
answer all 3rd party questions and EOC questions ( at least twice)
make flash cards of formulas and key topics ( keep everything brief you need to be able to remember the key concepts)
try and do multiple old cfa mocks and old am tests
take two weeks off if you can and study 8 hrs a day
i found this was a efficient way to study as I worked full time, have a wife and son, and enjoy time with friends and sports. I didn’t have time to read the CFAI books and between 3rd party and EOC questions I haven’t seen anything that wasn’t covered.
last year I failed band ten I did the above but without flash cards and I didn’t do a single mock. Last year going to into the exam I thought I knew it inside out, wrote the exam and walked out feeling like shit. I was surprised I even got band 10. This year I i know I knew the material way better. Found AM semi challenging time wise and question difficulty, finished with about 15 minutes left. Found the PM easy finished in about an hour, taking my time and slowly reading each question for wording tricks. Left the exam with a smile on my face knowing I probably passed. AM: two <50, 3>70, PM all over >70. I don’t consider myself to be super smart and I found this to be a efficient way to study and still have a personal life, except the last two weeks in May. Everyone is different but I found this effectively covered the material to the extent I have ever seen it tested or questioned. Hope this helps good luck
