So I'm doing bio, chem, maths and further maths and it's definitely getting too stressful. I have two fm tests coming up this week that I have not revised for at all, and one of them will basically determine whether or not we can continue further maths. Everyone in all my classes are ahead of me; they've already read ahead of the lesson, are doing so many other extracurriculars and are way ahead of the teacher in class. Meanwhile I'm sleep deprived, consistently late (I've already got a detention on the first week), struggling to catch up with what's happening in class and I can't seem to remember anything we've been thought. I'm still debating whether or not I should drop further maths while others are way ahead. I've tried to organise everything, create to-do lists, schedules etc, because I kept missing and forgetting when I had a class, extracurriculars etc, but this has only taken up more and more of my time. By the time friday comes, I just end up sleeping the whole day to catch up on sleep, and I just don't have the motivation to do anything for the rest of the weekend because I'm burnt out.
Any advice on how to deal with this/be more productive??? I really do want to continue further maths but we get set so much homework, which takes me longer than average to complete as I'm not good at maths. I would still like to do further maths, but is the workload too much??
