Save my bio exam

So I do A level Math, chem,bio. I got a D in bio, B in chem, A in math in my mock.How should I balance my study between these 3 subjects(I spend little over a day to study math and chem, but some how get those grades, and a week to study for bio but get a D).As I must need an A in bio to get to my dream uni.
Also, any tips for biology, although I feel like I know the content, I just can’t get my head around the randomness and vagueness of mark scheme. I don’t even know if it’s possible with only little over 2 and a half month
Any tips and help is appreciated, thanks in advance

Hey hey @Thxxdr , I hope you are great. Two and a half months is actually plenty of time to move a D to an A in Biology. I remember I struggled with it too, but I managed to move up.
The issue is not effort, it's method.
I would suggest balancing your time well. So, instead of spending more time on Bio, you need to spend smarter time. So giving Bio enough time is essential. Because remember, you can know the content and still lose loads of marks. You need to focus on:

What actually boosts bio grades fast:

If you do this by doing past paper questions almost daily, analyse every mistake and learning mark scheme language it is possible to improve your grade. Biology is actually one of the most improvable subjects once exam technique clicks.
I totally believe you've got this and I wish you all the best 🙂
