    i'm sure you've done great, you get lots of method marks and most people found it hard so boundaries wont be too bad, don't stress!

    Went horrible for me, pretty much had a mini nervous breakdown because i just couldn't concentrate :') people found it quite difficult at my college. I think, the worst mark I could have got would be 46/72. I've worked out the average grade boundaries from the last 14 exams, if anyone is interested; 57.3/72 = 80 UMS (A), 49.4/72 = 70 UMS (B), 41.6/72 = 60 UMS (C).

    So annoyed because every past paper I was doing I was getting 85+ UMS. Hoping for low grade boundaries but not getting my hopes up. Bad day, peace guys.

    I love how the last question in this exam is really similar to the last question in the 2014 M1 paper that everyone complained was difficult so OCR decided to add a pulley this year, because that makes it so much easier...

    Where did you get 5.99 from? Wasn't it 0.599 because it was time taken to fall?

    Highest grade boundaries were 62/75 = 80 UMS, 54/75 = 70 UMS, 46/75 = 60 UMS.
    Lowest grade boundaries were 52/75 = 80 UMS, 44/75 = 70 UMS, 36/75 = 60 UMS.

    0.558 was Fmax, seeing as this is bigger than the pulling force, F would have matched the pulling force. (Friction varies with R up to the maximum value of friction). As friction would have matched the pulling force, there would be no overall force. I think!!!
