Do the grade boundaries come up before or after the results?

with this kind of biology exam im fearing the chemistry will be like "why did avogadro name a mole of gas a mole instead of an octopus because to hell with your revision"

I'm not sure. I think it was the day before last year, something like that anyway...they basically come out at the same time.

Was a thread like this and twitter so active last year? I've seen previous IGCSE science threads and I haven't seen so many pages before. If not then maybe this is kind of a consensus that edexcel really went wrong this round..

what did you guys write for those yield question of why dry mass instead of fress mass and why % instead of that kg m s something?

I put to ensure they are put in a warm and dry environment and then weight them but I feel it wanted a more complex answer

Since all of you are taking chemistry on thursday, any predictions? Just so that I know what not to revise- they will be totally unpredictable

For the first I made reference to water molecules in the plants
For the second I wrote that some areas may have a denser population of plants than others.

Bare in mind that I was rushing because I found it hard and left it till the end

Don't worry there wasn't, that started off as me thinking testosterone causes sperm production, then someone said no, it's fsh or lh...it's okay, you didn't miss a question out!!!

Tbh I thought it was pretty fair. Sure there were lots of suggest questions but I felt they quite a few topics were covered and that lots of the past papers were much harder. Look at the jan 2015 paper if you want to see a really hard one. This is obviously just my opinion though

For the difference between lowland rice and upland rice I said they were genetically different, is this wrong ?

Yeah, I'm genuinely worrying that I didn't lock my people in a room with mosquitoes, I just let them do their own thing - never thought THAT'd be something I worried about!!
