How did you guys find it? Personally I probably got less than 50 percent, I left so many questions blank, but that's just me because I haven't taken this course seriously at all (also lots of problems last year due to COVID and internal school stuff). Don't think many people do it but here's hoping that some people can share their opinions on it. I, for one, did not find it great.

I'm so glad I'm not the only one! I applied to non competitive unis but I still need at the very least a B if I want to get in.. oh dear... I'll have to hit the grind for decision mechanics and stats..

Feel like it wasn’t the hardest paper ever. Compared to some of the older papers I thought this was a bit more doable but there were a lot of things I could have answered but didn’t because of gaps in knowledge. Hoping grade boundaries are lowered. Glad to know it’s not just my school doing OCR MEI B.

Oh, I'm surprised to hear that! I actually thought the 2019-2021 papers were a lot easier than this one. But then again, yeah maybe it's due to content gaps, it varies from person to person. I hope grade boundaries are low too.

Anyone remember the answer to the first order differential equation question worth 9 marks. Dy/dx(4-x^2)^1/2 + xy = 1 Think that was the question

is that the disgusting one where you get like (4+x^2)^3/2 on the other side, fairly sure i gave up at that point or something i cant even remember , i probably did it so wrong
