Should DD sit Biology on Tuesday?

[stayathomegardener]

DD is currently sitting GCSE's, needs 4 B's 2 C's to get to her chosen college.
Currently already has a B in Stats and A in ICT, she is pretty confident in getting the other 4.
The crux is she has Biology and PE next week, neither of which she is well prepared for.
Would she be better not sitting Biology to focus on PE and upping her predicted grades in other subjects? Or going for Biology on the basis she got 2 marks of a C in a recent mock.
She is dyslexic and revision/ short term memory is a problem. She also tends to overload.

Yes as I said previously, this thread gave us the information she needed to make the decision.
Exam sat on Tuesday.

That is indeed some honour, stayathomegardener - There have been some truely mad ideas on MN!

Hope her results are OK!
