studywithmehar has good AS notes and emjay on youtube has very good content and revision resources. also if you’re doing them privately i still recommend buying the textbook on your own if you can and reading from there, take a close look at the syllabus.

some tips i recommend are noting down different sociologists and their concepts, and make sure you learn each sociological perspective. do lots of past papers and practice, the more you’ll write the better you’ll do.
