    yeah in the first year. We did this paper as a mock about two weeks ago I got 60. I messed up on that 5 mark question about making salts and the page after that. I found this and January 2010 to be the hardest

    Same! I want an A in this as i've heard unit 2 is a killer. June 2012 was one of the easiest I've done, the grade boundary was high as well 66/80 for an a. As it was the most recent paper i think they will give us a hard one as that was too easy!

    sorry, how long have you been revising for?
    I know I always think that too! Whenever there has been a easy paper the next will be really hard -_-

    lol yeah I find psychology easier to understand and the papers are not that hard but there are too many studies to remember which annoys me! I've covered most of the content i just need to learn the specific information about studies now. I also hate the day care part

    Yeah by far psychology is my most easiest subject. My teacher told me that an A is 70% which is low compared to other subjects!

    Same there is so much to learn!!

    Yeah day care is the worst part for me as well -_-
