    I can do them over my long break or email the paper to PM and he can (my school gets the papers). I'll be doing the IAL one anyway to see how much I need in FP2/FP3 to get an A*

    Jan 14 IAL Q6b.
    The question says 'less then 2pi..' and not less then or equal to so I used tension>0 and not >=0 the mark scheme as it seems doesn't seem to address. also technically this time can't be achieved can it as implied in the mark scheme?

    Also are solomons worth it? Hardest ones? Are they harder then the IAL/R papers.

    I think they are confusing the criterion for complete circles.

    Strings - tension at top > 0.

    Rods - speed at top > 0.

    This makes intuitive sense since rods cannot exactly go slack or anything, can they - so the condition is that the rod must have a velocity at the top for it to perform complete circles whereas strings can go slack so the condition is that tension at the top needs to be greater than 0.
    Yep thats what I was thinking. Thanks for clearing it up

    Well i know bits of hypothesis testing i just don't understand it at all. I got 83 in S1 and S2 49 cause I knew I only needed a few marks on S2. I need a B ish in S3 and 8ums in S4. So hopefully i shud be alright if and only if o gather 290/300 in M3-5. Lol.
