i'm a struggling year 11 student. GCSE's are in 4-5 months and i'm stressed. i know i should'nt be but... i'm unsure on how to improve. how do i make a routine and stick to it? how do i sit down and study and be motivated and willing to do the work? i need some help and im scared. i zone out a lot during class and when i study (and even during mocks) i think i have an issue like brain fog or i might just have adhd.
