I recently started my AS levels and I'm studying biology (CCEA), history (CCEA), psychology (AQA) and religious studies (CCEA). Already I've noticed an increase in workload and more complex topics but i'd really appreciate recommendations on when to start hardcore studying for summer exams (and also any tips for any of the above subjects or for alevels in general)!
If you want to aim for AAAA, revise now.
Now. Not hardcore revision tho.
It's never too early, but it can be too late.
What would you prefer too early or too late?
Start now and make it a habit. Come exam time everything should be easy to you and you just have to quickly revise things.
Therefore you can go through subjects quickly and efficiently and focus on your weak points rather than focusing on the whole subject if you didn't revise constantly throughout the year.
Starting now should reflect in your grades being higher.
The important thing is to make sure you actually know and understand the content as you go. Otherwise, you'll be lost further down the line.
In other words, revise now but you don't need to be cranking out past papers yet.
take this from someone who made this mistake and started revising january.... start now. create notes, do past paper questions and something no one told me (science in general) but look at exam questions which have nasty twists in. I couldnt do them as the lessons just made me hate myself and i couldnt deal with getting more stuff wrong but it wouldve been better if i did. Exams LOVE to give awful little twists, varying from confusing contexts to straight up super confusing question layout or even questions that look like theyre off spec!
TL;DR now, take it from me (got my AS', not very good) i started in january and didnt do well. Start basic now, no more than an hour per subject, give or take 30 mins if you struggle or not
