Unfortunatly I think it could be anything! The only way to be sure that your essay mark will be high is to revise all the main principles from every unit. I hate unit 6
And always have a look at the last paper they made (jan 2005?) to see what the essay question was then, as it WON'T be that one again. Its a small glimmer of hope in a very dark and horrible bio world... lol
LOL so true! In my january 05 exam, i predicted what questions might come up (excluding essays) by asessing the 04 paper, i was 70% right!
The Nitrogen cycle came up in 2004, and not in january 05, it might come up this year
Ah wow, we did that paper for our mock, and I totally forgot what the Nitrogen cycle even was lol. Needless to say, it wasn't a great success that paper! I just hate the way that you have to link several units together to get the marks for the essay question... i wrote 2 sides on enzymes and their commercial functions, all from the AS unit, totally forgetting about the genetic engineering part of unit 5 the mark scheme also wanted! DAMN THEM!!
