do i have enough time to get a decent grade in a-level chemistry?

my half term just started and i'm making notes from scratch for chemistry (and also finishing up notes for my other 2 subjects).
if i finish making all of my notes for my subjects by the start of april and then just do past paper questions until may when my as-exams start will i be fine? i'm not looking for straight a's or anything but would it still be possible to get at least BBB/BCC??

if you do aqa chemistry, just use the detailed and essential notes on pmt instead of making ur own

Personally i think making notes can be a waste of time because you're just writing what you hear and not truly understanding what your being taught. To improve in a subject especially for a level chem its better to start practicing questions right away. Attempt an exam paper, even if you don't feel confident, identify the topics you struggled with, then use YouTube and the mark schemes for help. A week later, try the same paper again to check your progress. This method allows you to start exam practice earlier and complete more papers before June. Also for Organic chem memorise the synthesis map it will save you in the exam!

Chemrevise has really good notes, you shouldn't waste time making your own. I started to improve so much more once I started doing daily exam question practice. Use the questions by topic on pmt.

doesnt cover all the spec points for wjec unfortunately
