I liked this test was quite easy compared to the mocks. I went blank on the gentically modified bacteria tho, was it restricted and ligases and the plasmid stuff :/

I think so

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

I put something about variation, might be in the mark scheme.. if the majority of people came up with a valid answer the examiners add it to the mark scheme in a meeting

Damn, I definitely went wrong then - I wrote about how the lowland soils had more nutrients than the upland soils. So far I'm the only one who wrote anything like that :eek:

i would say yes, as the question before was about high temperature denaturing it, so should be acceptable

Was I the only one who didn't know that hormones could be denatured? That was the hardest question on the exam for me...I guessed something to do with it being denatured, but it was a total guess

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...

That sucks, but they'll probably just deduct a mark or two and then go from there. It's probably not nearly as bad as you think!

It might be, it might not. Mentioning that the pH affects the active site of enzymes is for the full IGCE Biology (paper 2). I mentioned the pH in this question too coz I didn't know what else to write. Depends how exam board is feeling with questions like this.
