A level OCR Chemistry module 5.2
This includes the entire chapter of 5.2 chemistry (OCR, A level from 2015 onwards) that I personally use for revision. Best coupled with past paper questions (you can find online for free). The information has been taken from lectures and has been rewritten in certain areas by my professors. Incredibly good resource that I have been using and have achieved 90% and above in all homework and exams including this content and have so far achieved an A* predicted grade with this style of notes - I have this for every chapter.
