I would reccomend sticking to Schweser books, since they cover the material in more efficient way.
The most efficient way, hovewer, would be to learn the answers to all LOS, which Schweser is good for.
For example, I wrote down all study sessions main information and formulas and completely memorized the main points (provided in a list below) in a way that I could reproduce all the information in just 2 hours. This inforumation could be put just on 12 pages of handwriting.
After that you should solve 6-7 mocks and you are fine.
