The link Publius provided is good. Your resources are all over the place. You need to take Jennifer's advice and narrow it down.
I didn't use any resources to study for biology and chemistry, but I've taken 18 hours of chemistry and even more biology. My sister-in-law used the REA book and squeaked out a pass in biology. I'm comfortable recommending the REA book followed by the Wikipedia links I published (last link in Publius's post). Spend the money and use the Peterson's test to assess your readiness when you think you are ready.
I don't know what to tell people to do for chemistry other than take the Peterson's test to assess readiness.
