chem from b/cs to a - aqa

Some tips I used to use:
1) Create a study schedule (divide your time according to the subjects and topics you need to cover)
2) Practice past papers: (doing past papers will help you get familiar with the exam format, structure, and types of questions)
3) Analyze your mistakes (when you do practice papers, it's essential to analyze your mistakes thoroughly, this will help you understand the concepts better and prevent repeating the same errors)
4) Get help (if you have problem with any topic, don't hesitate to seek help from teachers, friends, or online resources)
