Looking for advice on Chemistry.
I'm sure you know this but...
Essentially a few steps that I'd say most people do:
1. Write
comprehensive notes to syllabus dot points using multiple sources (understanding the content as you do) - should use at least 2 textbooks, class notes if you think your teacher is decent
2. Memorise notes back to front (if you can get to this point, you should be at least band 5...)
3. Do many many many past papers to perfect exam technique + marking yourself and noting down mistakes/areas where you lost marks (the more past papers you do, the higher you go)
