Yeah, it's annoying (although we did have study leave for 2 weeks) but I'm staying home anyway, and I heard that more people at school are doing the same (I might have somehow influenced them lol ) :redface:

I think someone should look at all the past papers and see what 6 mark questions have been about? :redface:

There haven't been any 6 mark questions in the past papers from the old syllabus :redface:

Yeah, that was introduced into the new spec and the old spec didn't have it, so were going to be the first people to sit this exam with the 6 markers :redface:

Lucky- maybe your student population at your school is more trustworthy (we have to go to school in case some people misuse their time at home!) :tongue:

About 25 minutes on each module then 10 minutes on the last section.

For the menstual cycle, how would you improve this description?

What happens during negative feedback for the menstrual cycle?
When oestrogen levels levels are high, FSH levels fall. This is detected by the brain which then acts to increase FSH levels, but when the egg isn't fertilised, FSH levels fall and the cycle starts again. :confused:

And what happens to oestrogen and LH during pregnancy?

Section D is a new 10 mark section which is for data analysis and stuff like that - don't worry it's rather straightforward.

Not sure about negative feedback... didn't know it was one.

I would say oestrogen and LH levels are low, since oestrogen repairs the lining (doesn't need to during pregnancy) and LH stimulates the release of eggs (once again not needed in pregnancy).

Also progesterone is needed to maintain the uterus lining, which in turn inhibits LH.

So high oestrogen inhibits FSH whilst high progesterone inhibits LH?
