Schwesser notes.
I used the CFAI texts for level 1 and realized how much a waste of time it is. Immediately switched to Schwesser for L2/L3, saved a lot of time. You can even start studying in February too.
The notes go straight to the point and test maybe 95% of the material you will see on the exam. Key point is understanding every point in those notes!
I read each book once and fully understood concepts and finished by end of March, 2nd read much faster in April, May practice exams and you should be good.
Make sure you understand what you did wrong on the practice exams and even if you get them “right”, read the solution to see how the answer is written. Mark tough on yourself.
After an practice exam, adjust your schedule accordingly.
Looking back at it, I still think I studied too much, probably total 200 hours or less.
Level 3 is not hard, its just different. Then again CFA material is not hard at all. The main issue is recall on the writing portion, even then, some questions if you see the practice exams, its not fully 100% recall, you can pick stuff.
