1. Revise consistently from Year 12. Lots of students don’t do very well in Year 12 and that’s okay, but being confident on your Year 12 content by the end of year 12 helps as Year 13 steps up.
2. Do practise papers!!!
3. Ask Questions if you don’t understand! Understanding is the key to success as something you understand is much easier to revise.
4. Work during your free periods. Most sixth forms don’t have a Study period which you have to go to. My sixth form did and I found it helped. I didn’t have any free periods, but you get used to it. If you do 3 A-levels you should 3 lessons a day and 2 frees. Use a one free period once a day for revision, practise questions etc. This allows for consolidation.
I got my IGCSE results this May and managed to get 7 A*s and an A. TBH it's not that tough. All you have to do is revise all your subjects daily and try making notes in your words as that would help you remember things much faster. Always have detailed and organized notes which you can always refer back to. For sciences, I personally felt that reading the textbook thoroughly is the key. Always pay attention in class and use your free sessions wisely. When you are coming to the end of the year, START DOING PAST PAPERS. I literally completed all the past papers right from 2002 till 2019 for most of my subjects. Doing past papers will help you understand the exam pattern and will help you understand what topics are you struggling in. Don't pressurize yourself too much.... just put in the effort daily from day 1 so that you don't end up getting all the load a month prior to your exams, as that will never help you ace your exams. So just put in the hard work every single day and you'll be able to get your desired results
