    I did m1. I thought it was alright tbh. Few hard questions but nothing I couldn't do . I liked the one which asked you to find when the speed is 8m/s from i's and j's. simple bit of pythagoras and quadratics .

    I did both i thought C3 was alot harder than M1 even though when i started M1 i still had my calculator in radians so it took me a while to work out why my answers wasnt right.

    i only got 3.6 but i did mine by using pyhthagrous to all the i's and j's in an equation of motion so im guessing i got that one wrong, but o well that was one of them that i didnt really know what to do i just took a guess.

    Well did you use the equation for velocity for example  V = (5i +3j) + (3i +2j)t

    then use  speed = \sqrt {(5 +3t)^2 + (3 + 2t)^2}

    then set speed = 8 and solve the equations from there.

    Yes that is what i did i must have gone wrong when finding t but i suppose i should get method marks

    Yeah you should do well then . Do you do further maths?

    No i wish i had though, but im my school you had to get an A star to take it as a 5th a level and i only got on A so taking it would have meant not taking one of my other subjects and going on consortuim to do it were the maths department arent as good.

    Oh that sucks :/. It's really hard though!!! got my fp2,3 + 4 exams and I don't reckon I'll get an A in it .

    i found M1 really hard. thank goodness for the 'show that' questions. But i couldnt seem to get the answers at all to questions 6,7,8. Im doing M2 now will this help if i want to retake (if i have to retake) for M1? I completely got the time question wrong in mechanics though!

    C3 was soo much more better but then again i could have messed up on question 7. fingers crossed nothing major.
