This sounds awful, but you just have to think of results day, opening that envelope and seeing what you want to see, what you have worked SO hard for and also what you need to get to go into your choice of 6th form (if that is what you want to go on and do). You can't give up at the last sprint of the race when you are doing so well already!!! I don't know if this will help you, but I spoke to a friend of mine who finished his A-levels last year with all A's/A*'s and I asked him how on earth he kept himself so motivated throughout - he just worked, worked and worked. He told me he watched motivational videos to get him in the mood and it really worked for him, so maybe you could try that. Just don't give up, you are sooooo close to the finish line and we all know how tiring it can be, getting up every morning to another day of revision just seems so awful but you're going to have one of your longest summers yet and you will feel so much better coming out of those last two exams knowing you couldn't possibly of done anymore. So have faith in yourself, give yourself regular breaks and KEEP GOING! It will be worth it in the end I promise you. If you are tired of writing things out in note form, try revising a different way - use flashcards and get someone to test you, get in contact with classmates and discuss things, like the person said above ^ watch revision videos. Have faith, you can do this!!!
