2 years after being passed out of A level, i feel that many kids spend their time confused.
Some teachers just convince them that they can't do it, ruining their confidence. They do it so that the same kids come to their academy in evening to magically become intelligent again.
But there are also some really caring people out there,
The conclusion is to try and do most of the things yourself. Do your past papers but don't ratta them. First go through the concepts, read the books and notes. Then attempt those past papers without cheating on yourself, don't peek at the marking scheme until you are done. You probably wont get results immediately but you will get them when it matters.
Dont waste your time on academies. This age is to be enjoyed and memories to be made.
But never go easy on your math, else it will bother you for a long time. Some teachers teach it in an exam oriented manner, go for it in a way that you truly understand.
