AS Maths

Would anyone be able to give me advice.
Ive been really stressed and become super ill lately and ive fallen behind in maths after already struggling for a while. On average, I get Ds and Es in my maths modules. ive been working as much as I can, doing around 5 past papers a weel but im struggling with logs and differentiation (when there's areas and max/minimums. Not sure what its called). My first exam is the 18th May. Is there any chance of me improving. Do you have any tips? Id be over the moon with a B and content with a C. I wont get an A. Is it too late?

Rules for logs:
Logx(y)=z ------> x^z=y
Log(a)+log(b)=log(a*b)
Log(a)-log(b)=log(a/b)
xlog(a)=log(a^x)
When solving inequalities and you need to divide by logs, check whether it's negative because you will need to flip the signs.
When solving equations to find x remember that the objective is to simplify to a single log so that you can find the unknown.

That's all I can think of for logs really, the key is to practise until you become more fluent but don't waste time on a whole paper if it's only a few topics you're worried about.
