self study for bio?

Hi! I’m attempting to self study for bio because my school doesn’t offer AP Bio. I took a regular bio class last year that was pretty elementary… I have both the PR and the Barron’s books though. Will thoroughly studying these two books be enough? I did get the Campbell textbook because I’ll be using it for Adv Bio this year (I’m a rising senior so I won’t be able to take the full class before taking the subject test) and have been looking through it but I’m finding it has WAY too much information for me to study in less than 2 months, so I’m wondering where to draw the line… any advice would be great! thanks!!

The subject tests are not tailored to the AP curriculum. They are supposed to be for high school level _ subject. The review guides should be good for diagnostic purposes and if you find an area you are lacking in that is the part of the Campbell’s book you should read.
