I got a 9 on my bs section and want to increase it to a 12+, is the TBR bio the best way to do this or do you guys find it a little too hard?

Let me put it this way: On TBR bio I was averaging about 55-65% correct. I got a 14 on the real thing.

Personally I would stay away from TBR bio. The rest of their science books are great, but they really botched up bio.
