It was 42/60 for an A* for the same exam last year.

Let's hope it stays that way.

What did you lot put for the Hexa question, on why the boy didn't get the disorder?

I said his inherited a normal allele for synthesis of HEXA from his mum cos it's sexual reproduction... and the normal allele is dominant

Did anyone also find the invigilators bad?? Mine were constantly talking and breathing loudly, I was getting so distracted!!

mine didn't have a clue what he was doing walked in walked out 5 seconds later and sat in the office drinking tea

Basically, the allele he had inherited from his dad was recessive, and was masked by the dominant allele inherited from his mum. Therefore he did not get the condition.

Let's talk grade boundaries, I think:
A* - 45
A - 36
B - 24

I think they might be lower.... maybe 70%?? A*

I'm thinking higher as in my opinion it was easier than the paper last year. In the range of 45 A*

What did you put for the isomerase beaded question and the last 2 questions?

I put
They can be reused
and it's a constant reaction....

wow. I was so confused on that one. I wrote:

1. They can control the amount of glucose using the valve. This controls the amount of fructose produced (total bs)
2. The costs of powering a mixer are reduced and less fuel is used to power so it is more economically and environmentally sustainable.

ugh, I hated this paper.

A* was 48 in January

I put if they used a large container the balance between isomerase and glucose would not be correct (THE PROPORTION) and every drop of glucose gets the mixed with the right amount of isomersse I just guessed it

I put 46 as well. I got a damn migraine in the exam so completely screwed up the Question 8. What did you guys put for the last two questions on the paper. The one where it asked what suggests the species are ancestors and then the other about why the offspring could not reproduce?

not sure if i was right, gbut i said that the offspring was a hybrid..

hahaa

i put your exact same first point in a mad panic to write anything :') but my second point was that the beads would have a larger surface area (absolute bs!) for the isomerase to work on! ohhh dear :rolleyes:
