Find out what the time period is in which you can sit all your ATPL exams, someone mentioned above it’s 24 months? Sit all your exams apart from the easiest one, withdraw from the school, you’ll get your money back minus £5k, which is the cost of groundschool anyway, then take a year out completely and reassess. Given 2008 took 2 years to empty the hold pools this will be almost certainly longer.
I’d advise your coursemates to do the same. This is your opportunity to get out reasonably unscathed. Use it wisely.
Good luck.
