You should plan to cover all the topics over the next few days. For example, if you are weak in biology, read about it for a whole day. In mathematics it is the same verbally, and so on. Every school day should have 1-2 hours of training followed by a short break. Rinse and repeat, teaching yourself as much as possible.
