I would suggest you first read the Schweser notes and attempt the CFA curriculum end of chapter questions. You will eventually find that for some (maybe many) eoc questions, the Schweser notes are not in-depth enough, hence you will need to go back to the CFA curriculum for a more detailed understanding. It’s important you do all the eoc questions and practice exams thoroughly and when you come across questions where you don’t feel confident, study these in detail from the CFA curriculum. For essay format questions, it’s important you do the practice exams UNDER TEST CONDITIONS. I found that for both L2 and L3, there’s no substitute for starting early.
