Maybe I've done so many papers I don't remember which year is which xD I copied out the mark schemes for that particular question so I'll be ready for it lol

Yh I just hated that one, and its the kind of thing they might test since lots of people, inc me(!) consider it kind of an unimportant topic

Also, do you need to know how a biogas generator and how biofermenters works?

I think the 6 marker will be one of the following, these are quoted from the specification:
Evaluate the use and development of using artificial aids to breathing including the use of artificial ventilators.
Analyse and evaluate the conditions that affect water loss in a plant.
Given data and question will be, evaluate the claims of manufacturers about sports drinks - about whether they hydrate better then water and all that stuff.
Evaluate the use of stents, artificial hearts and heart valves.
Evaluate the advantage and disadvantages of treating kidney failure with dialysis or kidney transplant
For the second section of B3 that incorporates geography topics if u look at the spec there are questions there that could be asked. These are just gueses of what may come up.

My targets an A*. My biology teacher said its likely that the grade boundaries will be slightly lower as normally people have modular exams so have four chances of sitting them (june and jan yr10 june and jan yr11) as we are taking all the topics at once, we may have lower boundaries for a star.

I only started revising about 1 & 1/2 weeks ago, cause I was doing my computer science revision before that.
Mostly I have been doing past paper this weekend, and last weekend I revised by watching all of these videos (www.my-gcsescience.com), and making a sheet of colourful A4 notes for each one, then after I went back through them and added class and revision guide notes. :smile:
