    That was such a good paper. The boundaries are going to be so high. This was the kind of paper that will cause you to drop a grade for 2 little mistakes.

    NOO don't say 57/60 for an a*! A* is usually 6 marks above an A. Let me check the highest it's ever been for an A* I'll get back in a second.

    I wasn't sure on that one, but I put steric acid which is saturated because you couldn't know whether the other two were trans or cis?😕

    I wasn't sure either but it said they were naturally occurring, making them all cis I think? That's what confused me
