Hi everyone, Ok so I have a small question on the concept of self-teaching. When I just started university this year I was mostly interested in Biology, a bit in chemistry and hardly anything in Physics. Over the year though I have noticed that my interest in certain fields of Chemistry and Physics was increasing, Mostly Chemistry though. Also over the year I noticed that my Chemistry knowledge seems to be lacking, even though I read everything and understand it to a certain degree and can do most of the problem sets I still don't do well on tests or show that I know the information. I believe the problem may be that I am lacking in the ability to generalize the information that I obtain, as in being able to apply it to different yet similar scenarios or problems. My answer to this was to re-teach myself Chemistry and Physics over this summer, starting from now as well, although won't have a lot of time as I need to prepare for finals as well. My current intro. Chemistry course uses the textbook: "Chemical Principles" by Steven S. Zumdahl. I was thinking of redoing the whole book again and then moving on to other textbooks at the same level and later on advancing into tougher books and materials. Now I was wondering if you all good give me some books that you all think are good texts to learn from and increase my knowledge and abilities in Chemistry, and Physics if possible. Also if you guys have any tips as to how to better increase my understanding, so that I can apply the knowledge to all scenarios that would be wonderful. Finally, do you all recommend taking notes from textbooks or just try and understand? Thanks again for the help, and I hope this thread can help others too.
