The only trick i can give you is that slow and steady wins the race, 4 hours is enough to get things done, AS biology is not as hard as other subjects (in my opinion) there are 11 chapters only and around 45% of the content is the one you've already studied in o'levels or IGCSE. For physics I'll have to say be consistent. as far as AS is concerned, Chemistry is the lengthiest subject it'll feel relatively easy in A2 as a lot of A2 chem is heavily linked with AS chem, so if you have a good grasp on that, A2 chem will feel like a walk in the park (but be prepared for the rollercoaster that AS chem is bout to give you). For A2 biology and Physics youll feel a jump after AS because the syllabus content will increase I can't say much about the difficulty level as it is relative.And I don't have Math so that's all i can give you. Just try to stay with your class,there's no need to rush things but never put things off as they will pile up, A levels is not as easy as o'levels mind that,small efforts from day one is needed.There are a lot of YouTube channels out there dedicated for you particular syllabus (i can recommend some if like). Oh! And PAST PAPERSSS! Be strict while doing past papers, do topicals after finishing a chapter. A level mark schemes are less lenient than o level ones, stick to mark scheme wordings religiously (cram if you have to lol, this is coming from experience). And also remember that there will be tonnes of resources out there some free, some paid (like YouTube channels, notes, past papers etc) you can hoard as many as you like but nothing will be of help unless you use them honestly and properly. Id suggest stick to few resources only otherwise you'll feel overwhelmed and won't know where to start. Preferably use the resources your teacher recommends.Don't forget to enjoy too. Manage your time wisely so that you don't miss out the fun stuff while not hurting your academics. Hope this helped ignore typos if any and finally Good luck! 🙂
