I didn't think it was that bad. Most of the problems focused more on Le Chatelier's Principle, and a lot of times you could avoid doing calculations, and the majority of calculations you had to do weren't that difficult. Just estimate and use numbers that are easier to work with. You don't need to calculate an exact answer to get it right.
The only tough part for me in TBR OChem is getting used to IUPAC names and recognizing common molecules like acetone. The rest was easier than what I did in class.
TBR Bio is a *****, though. Physiology isn't so bad, but the Cell/Molecular Bio book can be crazy difficult. I crush biochem-related questions, then have to really push my brain when it comes to other questions.
I have no complaints about TBR Physics.
