I believe I will fail my A levels. What should I do?

I'm struggling so much with my a levels, business, applied science and english literature. The english is not even the one i wanted to do it was language and is so boring. The science is boring and the business has so uch coursework. I always end up completing coursework for each subject on the day before the due in date. Like right now i have a hamlet essay which is due tomorrow. Its not as if i hang outside and socialise or have a girlfriend. I am just stuck inside with no work done and i believe these are not what i should do. ONLY SENSIBLE ANSWERS PLEASE.
