I was quite happy with my results, got AAA in bio, chem and maths in the end, so my revision technique can't have been too shabby. This is how I've been revising:
- Start revising from the start. Some days I'll do 30 minutes a day, some days I'll do 3 hours a day, sometimes I won't do any revision at all today. Just go over what you did in your lessons that day, read the pages over, make sure you understand it all. If not, work at it until you do. If it only takes 5 minutes to understand everything, just leave it at that, and relax.
- In your free periods, actually do work. I usually do revision in this time. I usually alternate between bio and chem, and it just helps to refresh my memory so I don't forget things. I usually do maths solomon papers in the morning before college starts, just to try and slot some revision in.
- I usually save my homework until the weekend, but I don't do any revision at the weekends.
- Most of the time, don't bother wasting your time on pretty posters etc. Just learn it.
- Do all past papers when you've finished the syllabus. Then do them all again just before your exam. Memorise the mark schemes, key phrases etc. (Mostly applies to bio and chem).
I never bothered reading around the syllabus/reading examiners reports etc. I tried it, but felt like I was wasting my time.
Hope this helped!
