I took a year-long regular chemistry class at my high school last year (should have done AP then...), and it was extremely slow-paced and boring. That pretty much crushed my enthusiasm for the subject until I started reading Linus Pauling's textbook https://www.amazon.com/General-Chemistry-Linus-Pauling/dp/0486656225/ref=cm_cr_pr_product_top. I totally love this text, and I've decided to use it as a self-study vehicle (possibly for the AP test, depending on how confident I feel). Pauling does an amazing job of explaining things without unnecessary blabber, and the crisp descriptions are easy to learn from. Here's the catch: General Chemistry has a very low exercise/chapter ratio. I learn best when I work through problems, so this is a bit of an issue for me. Does anyone know of good, free online resources with many problems at about this level? Thanks!
