Oh love, if you cheat on these you're gonna be ****ed. Its not a competition with the rest of your class and year, the teacher doesn't really care, neither does the school. Its for you to do it, see where you went wrong, and revise and learn that. If you cheat, you're not going to know what to revise and you'll be stuck next year. Trust me, i was in the same boat up until a month ago (I'm in year 11).
