I did the right method but made a silly mistake for the last question. I’m actually very annoyed that the paper got leaked. Now there’s a chance we might have to resit it. Apparently edexcel maths papers get leaked quite often. They really need to do something about it.

Is it definite the paper got leaked? I've seen the tik tok but there's hoaxes on there all the time

In a nutshell, break the middle circle into six equilateral triangles. Find the area of the sector (angle 60), then subtract the equilateral triangle’s area from it, then multiply by four. Then subtract it from the two sectors to get the answer. There’s a picture on twitter somewhere explaining how to do it

No it’s true. A classmate of mine is in the server and saw it after the exam. She took screenshots and reported it to the deputy head

yep it’s definitely true, a few people in my year got sent the mark scheme before the exam (didn’t look at it though) and it’s almost exactly the same as todays paper

wait, how did they manage to get hold of the mark scheme?? Was it from the person on the revishaan discord as well or from somewhere else?

The complete full mark scheme or just for the last question? Because if it's just the last question that got leaked probably all that would happen is the question is void and the paper is out of 75, but if it's the whole paper...
