Great chemistry links- Do check these websites out!
- 1. The World Of Chemistry - This website is an excellent resource of videos to make chemistry more interesting for you :)
- 2. Rod Beavon's chemistry pages... this site is really really good. Rod was the chief of an A lvl exam board, so you must check this site out.
- 3. chemguide, good for quite a bit of the A lvl basics
- 4. Virtual Textbook of Organic Chemistry - Like what it says, it is virtually a complete undergrad organic chemistry text book. From MSU, a must read for H3 students
