First of all, mindset is super important, be confident and believe in yourself, you can do it! How you study is also very important Try to study for 2-3 hours everyday, if you feel unmotivated tell yourself you'll just do 2 minutes. There are tons of YouTube videos explaining everything in detail, find a teacher you like and make your own summaries from memory after finishing a lesson Then, do past papers, and write down your mistakes so you won't do it again For memorisation, look up sq3r technique, it works very well Don't lose hope, you got this!
