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! :smile:

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

lol i don't trust the guy on stuff like that! He said the highest you can get by using the revision guide is a B!

I put male and female on the bottom in the little bars and then put the years on the bottom too underneath that :')

it told us that it was a protein and the stomach produces pepsin, protease so u had to mention that i think. I just wrote HCL though

I can't believe it....

I didn't fully read the question in today's IGCSE 1B.

I drew a line graph/frequency polygon sort of thing when it said in the question draw a bar chart...

SIX MARKS.

THAT'S 5%...

Someone please please help me...

how did you all do on the last question? kinda weird bc i said let 50 mosquitos loose and see which person attracts more of them but they would have got stung if you did that so i put make sure you wear a safety net but weird question lol

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! :biggrin:

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 :redface:

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... :redface:

I only missed out one question... the one about low lying and high lying crop yields (1 mark) :redface:

and I thought I would have been done badly, but I don't think I did :biggrin:

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.
