I'm currently in year 13 but in my AS exams I got AAAA in Biology, Chemistry, Psychology and Religious Studies (dropped this year).
1) Did you make notes everyday (typed or handwritten) as I make a combination of both
Personally I only made hand made notes just cause that's what I prefer. I'd make concise notes in class based off what was said and what was on the board and colour code the important parts. If I didn't understand a concept I'd then make extra notes from the text book or chemguide to consolidate it.
2) Did you make flashcards/mind maps
I made a crap ton of flash cards! I just find them so useful and easy to make. You revise while writing them and then you can use them over both years, especially important in the new linear courses. For example I'd write on one side "What does 'Anti-Parallel' mean?" then on the other side "The two strands in DNA run in opposite directions. One runs 5' to 3' and the other from 3' to 5'."
Mindmaps I didn't use as much but they were helpful in biology and RS in consolidating knowledge as they were both very content heavy. Mindmaps just aren't my way of doing things I guess.
3) Did you revise in free periods
I used my free periods to either catch up on homework or to make flash cards. Sometimes I would do past papers in my frees but a lot of the time I'd save them for home when I could time them properly. I only had 2 free periods last year but this year I have about 6 (off the top of my head) and being completely honest if I had a free first or last I'd either sleep in or leave early! (Not the best use of time, I know, but I live an hour away from sixth form so I use that as my excuse lmao)
4) How much did you revise on weekends/weekdays
I'd try to revise a few hours each day except Fridays which I kept as my break day. I'd obviously do more on weekends cause I had more time. This year me and a mate go to our local library straight from sixth form on Tuesdays and from about midday on Sundays. If you can do this I'd highly recommend it cause it just meant less distractions for us so we ended up doing more work!
5) Any other tips
Past. Exam. Papers. They will be your saving grace. You can know every last inch of the textbook and still not do well if you're not used to applying your knowledge. Learn what they want you to say as markschemes can be
very picky (*cough* AQA *cough*). Do old spec, new spec, legacy, basically whatever you can find but don't do them all now. Save some for closer to the exam period.
By the way if you're on AQA they've removed all old spec papers from their website but you can find them here:
