Maths-5
Physics-4/5
Pe-6
History-7
Further maths-6
Computer science paper 2-3
Business-9
I have 67 days left till my first exam and I’m worried I want to make my parents proud and get majority 8,9s with 7s in history and pe(due to practical not being great). Usually maths is my best subject but I don’t know what’s happened . I really need these grades . I’ve spent all my time till now procrastinating and now I don’t know what to do . Is it too late to make notes on my subject and make flashcards . What do I do for each subject to get these grades I’m willing to put it all on the line I just need help and guidance .
Please someone give me some detailed help for each subject how I should revise from now to achieve the grades I want . I get my results Thursday and I’ll say what I got . I also do English literature but they didn’t do a mock for that

split your time based on what you got a lower grade then use premade resources (flashcards mind maps etc) on seneca, physics and maths tutor, medley and anki or other websites you find useful to test yourself/ actively recall information making it easier to learn/remember the content. next PAST PAPERS do a past paper for each subject them mark them this can be with a walkthrough on youtube or the markscheme. when you have marked them on the markscheme it has the topic of each question on the specification( to find this search up the topic then the exam board then GCSE) so if you get a low mark on the question you know exactly where to revise. this can be by blurting (writing what you know on a whiteboard or piece of paper for a topic then filling in what you got wrong with a different coloured pen until you get it all right) , teaching someone else (for concepts), or re learning them doing a topic specific question to apply the knowledge (mostly maths,science,PE). for essay based subjects complete a past paper a week then give them to your teacher to mark and add CTGs (closing the gap tasks). To remember quotes you could use Mr salles or first rate tutors to get key quotes for characters/ themes which can apply to a range of question use blurting/ flashcards to remember them . for maths you could also do corbettmaths 5-- a day and then correcting the ones you get wrong. Overall i think you are definitely on track to getting 7s,8s, and 9s you've just got to be disciplined these last few weeks. Also you could input your current grades into chat gpt and what you want in each one so that it can generate a timetable that you can follow. If you feel unsure of how to start just start. sit at your workspace and work on your CTG tasks . dont forget to take frequent breaks though away from a screen- walks baking reading puzzles painting etc.
I hope this works for you. I have faith in you!! (also sorry for the potential spelling/grammar mistakes)
update me for what you get in your mocks and gcses.
