I took the first part of the college-level introductory chemistry classes (it's CHEM 1211 here). I took it a long time ago - 2002. When I took it, I didn't pay attention, it's a miracle I passed the class at all. And now I need the second part of the class. I'm worried that I'll be missing vital information because of this, but at the same time I really can't spend the time or money in the Fall to retake that class. I've got a little under two months before Fall and not much to do now. I'm wondering if anyone can recommend any good resources for delving into this material by myself - I can really spend upwards of 3-4 hours a day if needed over the next few months. I imagine there's material over at khanacademy, so I'm going to check that out. I wouldn't mind hitting the major topics out of CHEM 1211 and maybe crash-coursing through 1212 too. I do have Physics I and II under my belt and I did very well in those classes, so I feel like I know how to learn science material. I just need to find the best resources. Thanks for any help.
