Hiyaa.
I'm so sorry this is so late
So I didn't go to a grammar school or anything- just a regular sixth form
Trust me, I'm no alevel expert, but I hope this helps in some way
So for Biology I know a lot of people read the book and made notes (using the endorsed textbook) during the year. If your teachers haven't given you guys specification sheets, print them out !! Use this as a checklist before exams. They are not likely to test you on things that are not on the specification.
Make sure you UNDERSTAND every single point on that spec sheet before your exams (tick off during revision period). You can even ask teachers to specify what points on your spec sheet they're testing you on before any assessments and use that to revise specific areas (read your notes/solve pp questions based on that module).
Closer to exam period you need to do past papers and look at mark schemes so you get an idea of what examiners are looking for/how simple or detailed your answers need to be.
I remember solving past papers and then-if I marked them- I would do it with a different coloured pen, listing (down the sides) any additional points from the mark scheme (even if the answers were right) and the night before the exam maybe sit down and go over all the papers you've done, reading through those additional ms points.
And LISTEN in class!! (I knoww, it can be hard with Biology, I found Bio so boring! But helps a lott and will really reduce your work load). I made notes in class (because I was too lazy to come home and make them). Don't leave that place till you're sure you do understand! (there is a lot more understanding and application in y13) ASK your teachers questions, that's what they're there for, they want you do do well and they'll be happy that you care!
Chemistry is really enjoyable at Alevel, as long as you understand it. It makes sense and actually gets you to think a bit for yourself. A lot of people didn't like it for that reason I think, sometimes I guess not understanding a concept can be frustrating so people turn against the subject 😁😂, but nothing is impossible to understand (esp at this level) so never give up! Once you finish a topic in class, do any homework set on that specific topic (our teachers gave us past paper question booklets, but if you don't get em, these topic based questions must be available somewhere online). And put EFFORT into the hw, pleasee don't write something down if you don't understand it. So say you finished Alcohols today in class, go home and do those homework exam questions on Alcohols (try and do that before you get a test on it). Helps consolidate what you've learnt. Trust me, even if you feel like you 'can't' answer the questions, USE the markschemes (its not cheating!!)-same for Bio. Eventually you'll find you don't need the markschemes for that specific topic because you learn what examiners are looking for and start thinking in the mind set they want you to have Again, LISTEN in class and make sure you UNDERSTAND.
With planning, you need to find what works for you. I never could follow a timetable, but I found setting myself (short term) targets, much closer to exams worked a lot better. I used the notes section in my phone; Sort of like a checklist? it usually looked something like this:
17th June:
Read bio notes on f214 (half an hour)
Bio past paper f214 (1.5 hrs)
Chem past paper f325(2hrs)
In year 13 I also had different post it notes for each exam with checklists of all the recent years past papers for each unit and I'd tick them off so I knew how many I had done.
i.e
Chemistry-unit 4 (F324):
Jan 2012
Jun 2012
Jan 2013
Jun 2013
Jun 2014
Jun 2015
So I sort of had a record of what I had done and felt more on top of things, less worried. Maybe keep a record of your mark in each paper and redo the ones that you didn't do as well as you would have liked in? I know some people did solve the same past papers multiple times, but that didn't work for me because I'd remember every single thing from the first time (and the ms)-so it was a bit boring and pointless- andd I would never have gotten enough time to do that many papers because I was usually really late starting the whole 'revision' thing.
I guess these tips would be more useful closer to your exams/mocks but I hope they help in some way 😁😊. I think the key with Alevels is to understand in class and then try to perfect your exam technique.
If you have any other questions, do ask. Good luck
