Of course there is time, do not underestimate yourself or throw the towel in. What's happened has happened and the best course of action is to wake up tomorrow with your game plan on. Write a list of what you want to achieve that day, and then do it. Don't think about all of your A levels at once or you will feel overwhelmed and like it is too much. Just focus on each day, clearly defined tasks like 'do X past paper' 'read x chapter and make notes'.
