Is it bad to make mistakes in maths? I mean when I'm doing an exercise out of a textbook I'll do a question check the answer and 35% of the time it's wrong, I then go back and do it again and about 5% of the time it's wrong again. I usually have it right by the third go. I'm guessing this is bad because I won't be able to check the answers in an exam so what can I do to fix this. Buy another textbook and do questions out of that too?
BTW I'm using Cambridge 2 Unit Yr. 11.
