I only did around 1-2 hours before the exams for my mocks but if i revise effectively for 2 and a half hours daily and 5-6 hours on my Saturday's and Sunday's how many grades do you think i can boost up ?I am going to work through, reading my CGP books then read through BBC Bitesize and do quizzes, after i will watch good YouTube videos. I am hoping to do all that in the 1st month. In my second month i want to focus on questions for all my subjects and then in my last 3rd month I want to focus on past papers. Do you think i can achieve top grades ?
