    I agree. It was a pretty easy exam and they won't just give you the marks easily.
    Biology has the highest grade boundaries out of the sciences.
    Physics has the lowest grade boundaries because it is generally harder.

    Anyone find it harder than the old papers? Do you think the grade boundaries will get lower?
    Ocr 21st?? I found it quite easy, expecially the six markers about nitrogen and twins. I guess you never know how well you do until you get the results, so I'm sure you've done fine!

    I didnt find it too bad but the first 6 mark was a bit annoying. Lotssss of people got 87.5% increase for that disease increase question, I got 700%, anyone else? Also , that the way genes affect the drugs question where it says something about enzymes, i wrote something about how genes code for proteins and enzymes are proteins and some more stuff
    Hi, there was 700 so you are right.
