Haha I might just ignore whatever bio question that comes up and just write about the role of women in Jacobean threatre instead. That'll mess with their heads

Lol deserves them right, messing with ours...
Wish I could just interpret the biology essay to write what I wanted haha

Is it just me or is June 2011 horrible?

It's actually dreadful, the only good thing about it is that the grade boundaries are a bit lower than last year, hoping they don't go up again this year. Good luck tomorrow :smile:

As a topic on its own I believe it last came up in 2002. But obviously since then there have been essays on energy, condensation/hydrolysis, carbohydrates which it could have been used in.

The specification only states that we need to be aware of totipotent and multipotent
