i've spent so much time revising and studying during most of year 11, getting amazing grades for my mocks and class tests. but now that it's actually GCSE period, i feel so mentally tired and burnt out. i can barely sit down and revise since my brain will feel like sludge. there's barely any time to relax and let my head rest because i just really need to revise for the next exam and so on.
any tips to cope?
