As an example, by the time eight weeks had passed in my Access course (I studied Maths, Chemistry and Physics) I had already done about 1.5 units in each class with exams coming up and at least 4-5 assignments per class (some times you get an assignment
per week).
Also, a bit of background knowledge is cool, but an Access course is teaching you how to learn and think academically, referencing, searching literature and such. In my course you had three full days of study per week and you probably needed double the time spent in class to actually learn everything and do assignments. So you're looking at around 30 hours per week
just to keep up with the assignments and study you already need to do.
Doing a bit of simple maths, you will have missed ~120 hours of school time, then double that for revision/assignments/etc and that's 240 hours. Divide that by the time remaining in the course excluding holidays (around 30 weeks I'd expect) and you're looking at 35-40 hour weeks to catch up + do assignments + work on what you're actually trying to learn and remember your teachers
will not have time to teach you this stuff in any real capacity, because they're already so rushed teaching what they are supposed to be doing at that specific time
If you are suffering from anxiety, you can study A Levels part-time at home, even if you only do one to keep you busy it'd at least be something. You just can't do a 9 month course in 6-7 months and you'd be hard pressed to find a college even willing to accept you now, not to mention it could easily be a waste of £3000 (or whatever the course costs now) because you might drop out or not get the grades you want due to not having the time you need.
Fundamentally, it's highly unlikely you would even be allowed to enrol now. Had you applied to start in September you could have started studying whilst you wait for an ALL (Advanced Learner Loan) to be approved and at least then you'd have started and got it going, as it stands right now it's just too late. You need to find something else to do until next September, sorry.
