I'm really not looking forward to this, there's so much to learn and I feel like I know none of it It's annoying that the exams aren't split into unit 1 and 2 either

Literally learning chapter 6 and 7 today.. It's so long but I've almost got the hang of it. There's so much to learn so I just feel like I always forget the previous stuff whenever I learn something new. I have a feeling there's going to be a bit of application questions about either gas exchange or the cardiac cycle.
What ****ed me over in the specimen papers we've had for the new specification was how strict the mark scheme was! I literally know the majority of the content but I just don't write answers in the way they want me to 😡 It's so annoying. I've basically just accepted that I'm getting a U in these exams no matter what the paper or the grade boundaries are🙄
Guys I have a question about non-competitive inhibitors If you increase the concentration of non-competitive inhibitors then would this affect the rate of reaction? I think it does because- these bind to enzyme at a site other than the active site and when attached change the shape in a way that the substrate cannot bind to it. therefore less enzme/substrate complexes formed?

Is this reasoning right?? Thank uuu
You're right. It's also a good note to make that substrate concentration won't affect the rate in this case.
In paper 1 there'll be an approximate weighting as the following: 47-51% of AO1 35-39% of AO2 13-17% of AO3
where AO1 is knowledge and understanding (textbook stuff), AO2 is applying scientific knowledge and AO3 is analysing and interpreting info and practical procedures
Its a new spec so there is only specimen papers to revise from. Thats why the grade boundaries will probably be lower this year as nobody knows what to expect.
Hey has anyone got a rough estimate of what the grade boundaries will be for this. So approximately how much out of 70 for an A? also surely this exam doesn't count for anything since the changes? anyway good luck guys..
