ill need 80% for AS, my s1 grade would have let me down

You can get a C at AS and still get an A*. You don't need 80% in AS, you need 80% OVERALL, so if you were to get your 90 UMS in C3 and C4 next year as long as all of your 6 modules add up to 80% UMS you will get an A*. And that's given that you got an average of 90 UMS over two papers already. You're fine mate

You also have to get 180 UMS over C3 and C4 to get an A*

Mr. Raza

I agree; although I feel that EdExcel are increasing the difficulty of examinations under pressure from the DfE to increase calibre of the A-Level. They can't increase the course's difficulty until Sept 2017, so I am guessing they are reflecting the need for increase of calibre in the exams.Not fair!!! Are students being tested on what they can't do, rather than what they can do??Let's hope that Edexcel see sense and lower the boundaries.

For Q5b where they asked you to use interpolation to work out the median, I worked out the 25.5th value instead of the 25th. Will that be accepted in the mark scheme?

Do some of you realise that grade boundaries are calculated based on exam performance of every candidate lol. Saying "they should lower the grade boundaries because it was hard" is exactly what they do when results reflect this, because on average people get lower results. Did you people think they just randomly assigned grade boundaries before lol?

I expected better from mathematicians smh.

You've got to admire people trying to work out their A-level results 2 months before results day, though!

Yeah like you pretty much can if you remember all your answers :smile:

) I do that :wink:

It's just people saying "omg have mercy lower the boundaries" and genuinely thinking that a special effort will go into lowering the boundaries like pls stahp that's not how any of this works

I like it, you have a good, rational way of thinking like true mathematicians :tongue:

though I wouldn't know anything about that :rolleyes:

but to be fair, the stress of like exams and stuff drives people crazy and tries to get them to predict grade boundaries and count their marks and stuff when it's like, just focus on your other exams or enjoying your summer, ya know? :s-smilie:

I've got two questions. For the probability to win the game if I drew up a table of all the possible outcomes and got the answer to part i correct would I get 3 or 4 marks out of 4? I was checking my answers and realised I inputted the values into my calculator wrong but I was running out of time so I did 1-part i sigh for part ii. Second question is for the pmcc one I put r decreases because Sxy increases how many marks would I get? I'm not sure if that's a good enough reason.
