I did

pretty sure it had so much unrelated spec content

OCR have gone crazy about application. Completely unfair how hard these papers are compared to old spec. It wasn't the stuff you'd expect to come up either. Chi-squared isn't even in my text book. At least the breadth paper was better

Breadth paper was better... chi-squared is an A2 topic, which is just plain evil. But the chi-square question I found to be fairly straight forward( it wasn't too dissimilar to spear-man's rank). It's just there was absolutely no straight forward questions.

Yeah, the chi-square could have been worse but I probably got it wrong. The thing that irritated me is that I practiced all other statistical techniques but they chose to test us on chi-square. The chitin question was nice though. Don't think anyone did terribly in this one so hopefully grade boundaries will reflect this.

Chitin question was weird... I mean I did write stuff but I wasn't 100% sure on it.

I was literally how you would describe the structure of cellulose but obviously applied to chitin with that weird monomer. They kind of hinted at it because you had to suggest a monosaccharide that it was most similar too (beta-glucose). This is the only question i did well in lol

Yeah its not looking great for me tbh

Yeah I got confused because cellulose forms it's bond vertically. But the 1,4 glycosdic bonds bit threw me off as it suggested the bonds were horizontal. The 6 marker on enzyme was beautiful though :smile:

I accidentally got that question right.

6 marker on enzymes was beautiful if you knew what you were doing ( I DID NOT)
If its any consolation, when the new spec was introduced you needed 66% for an A on the second paper (2009 I think)

Well I was half expecting them to make us write out a plan for an experiment.. Which would have been the worst 6 marker if it came up. The other circulation 6 marker was horrible though. Do you hjave chem on Friday?

Yes, I'm not scared for chemistry though. Maths and chemistry are the two A levels I'm really good at. The 6 marker on circulation couldn't be any VAGUER. I think I got 3 marks for the enzyme 6 marker and 4 marks for the circulation one

Ah I'm weak at maths and didn't too good on the first paper. So need to make up with this one but it looks unlikely. I did revise enzymes thoroughly though as it didn't come up at all in breadth. About 4 marks is still pretty good. I only made 2 rubbish points of blood is not enclosed in veins and the double circulatory so heart beat can push blood to entire body. But I think you had to talk about gradients etc. which I didn't. If they asked about fish it would have been better lol. No point dwelling now though. Gotta do chem like crazy in the next two days.

Dropped 2 marks in my core 2 maths paper :wink: Yeah, I'll just do a few past papers for chemistry then and I'll revise S1 like crazy before the S1 exam. What examboards do you do? I do edexcel for maths and OCR A for chemistry
