A little late to thread but I agree with what everyone else is saying you’re in year 10, you probably should ramp it up on year 11.
About you calling it a ways of time, is what I disagree with. It is extremely difficult to go over something and become worse at it. You probably have mocks soon or have had them so this will basically check if the way you’re revising is good. If it’s not change it. Don’t know how to - speak to someone on here. To check if the new method is good do some exam questions or a past paper, although it’s better to save them for the end, but you can still attempt some.
Hope this helps although it may not be relevant anymore, but aleast it’s out there if someone needs this in the future
