Chemistry X: College and AP Chem

I mean this app seems helpful in someways, it covers very weird topics though, there is a lot missing. I mean ALOT, a majority of the things they teach you in this app is most likely not needed to know on the AP exam. Like where are redox reactions? One of the most important things in big idea #3. I think this app is good if you want to learn extra laws and equations but definitely would not recommend for preparing for the AP exam with this. I don’t know why there are so many five star reviews, you are better off studying in cliff notes book or class notes.

As a teacher myself (but one who knows nothing about chemistry), I must comment on this excellent book. It is clear, organized, and well-written. The authors have taken a difficult subject and made it understandable. I feel as though I am much better prepared for the college chemistry course I'll be taking in a few months - and I even think I will enjoy it! Thank you for this great little book!

They work out examples for the kinds of chemistry problems you see in AP and college chemistry courses, and that's the most valuable part of the app. I always come back to this app when the textbook is too unclear, the examples are too weak, or the teacher moves on to the next concept before we've fully figured out how to use a particular technique
