I'm annoyed that calculating Simpson's index, standard deviation, student's t-test etc didn't come up.

Oh no! I misread the question!

I put that the deoxyribose sugar binds to a phosphate group to form the sugar phosphate backbone.

doubt it will be higher than 56

it's almost never been at 80% for an A, 80% ums is usually about 64-72% overall,
I thought it was the Bohr effect

Expect it to come up on depth. It wasn't really likely to come up on this because these were short answer questions thats why I didnt revise it. So just be ready for the next one because it will be like 3-4 marks
for the source/sink question did anyone get 1 letter for the first one (i cant remember which) and 3 for the second one
