    I think you might be doing a different exam board or normal gcse as igcse only has two papers and the second is on the 5th June!

    Exactly what I said to Mr. Bates but he said "no Zahra I don't think so!" Ugh

    Oh I wasn't really bothered about their safety... I put leave 30 people from each group in a room full of mosquitoes and let them be bitten and then count the bites in the morning haha

    That question at the end about the mosquito experiment was fun! This guy next to me just legged that question at the end... XD I'm from Denmark, but a lot of people sat the paper. You guys may think we may not have many people doing IGCSE papers in foreign countries but gosh how many were doing it from mine school was crazy today...

    I was a little bit surprised about the question regarding the male reproductive organs and vas deferens... our teacher told us that there wasn't going to be anything like that in the exam...

    I only missed out one question... the one about low lying and high lying crop yields (1 mark) and I thought I would have been done badly, but I don't think I did

    How did you guys find the paper?

    Yeah, where it asked you to work out the percentage yield if one was 12 kg/m2 and the other 7 kg/m2 and it was the second to last question.

    Some people at my school wrote something about osmosis and putting the potato in a sugary solution so that all the water comes out of potato but I thought that was wrong
    Yup! I wrote that

    I put 41.7
    I put 41.7 in the workings and rounded it to 42 in the answer because the percentages on the previous page were to 2sf...
