Schweser book 5 or 6; I’m not doing as well as Id like on the sessions from those books so im going to reread one of them, which do you think will be more important for the test?

I assume you mean 4 or 5? Tough call since I think all of those topics tend to be around 5% of the exam… I would go for what you think you can tackle quickly first. Derivatives and GIPS I think are pretty long but execution is fairly short and probably the easiest to get on top of.
