    Hey, hope everyones test went well. One thing i dont get is how some people got the percentage increase when the number went from 4 to 19 (i think thats what someone said) as 55.56%? I read the numbers as 4.4 to 20 and worked out the percentage increase to 354.5%... Help
    I got 4 to 9, not 19.

    i put : faster mitotic cell division therefore damaged / lost cells of the lining are replaced at a higher rate
    Yep, I wrote something similar. "cells divide by faster so new cells are produced faster to replace old cells, as friction from products of digestion damage/remove cells from the intestine wall"

    I have a habit of not wording things as simplistic as possible :rolleyes:

    What about why they measure it per week? I got those two, but they asked why it was per certain time too.
    different length of the course of treatment?

    URGGH! I know right!
    All those HOURS I spent trying to learn the cohesion-tension theory and apoplastic/symplastic ways by heart. I think I might resit this unit JUST so I get to write about those.

    i think they want you to refer to selection pressure, where non-resistant bacteria are killed and resistant ones survive and reproduce.. blah blah blah
    Oh, ok that's what I put.
    Hopefully I'll get full marks for it.

    Same here I even bothered to revise why the circumference of a tree decreases under tension...

    Meiosis didn't come into it too, and the inside of the chloroplast and there was barely anything on blood vessels, nothing about fish or spiracles...

    Omg noooo! I put high affinity at first then crossed it out. OMG!
    I HATED that paper. It had nothing on the things I actually revised on (and liked), like immunological processes and xylem and phloem and cohesion tension, etc. URGH! So pissed off.

    Gotta ace the Chemistry tomorrow!
    i hope you realise immunological processes are largely in unit 1 and any stuff in unit 2 related to it is relatively simple...
