    LCAT isnt difficult but owing to the number of people who apply, you need to ace it. SSE is a bit difficult without the calculator though, especially the Advance Mathematics part. Still doesnt matter cuz i recieved the offer :)

    Physics p33 errors

    The one involving the Viscosity would most likely include errors, theyre the usual like: Inaccurate measurement of say time, (due to human reaction error) remedied by using Light Gates etc. Or something like 2 readings arent enough (depends on the question), plot a graph with multiple readings

    Small Nov 08 Maths p3 problems.

    After getting 13sin(x+67.38) you just modify this to 13sin(2x+67.38) and double the range from 0-180 to 0-360 (final range is 67.38<0<427.38) after adding 67.38 to the upper and lower limits of the range. To verify part II in 8 just use the RHS side taking the LCM and simplifying the equation...

    Mechanics PAPER4 2009/ 41

    Another method is that, you can resolve the 5N force into 2 components which simply leads to 5sin36.9=T2, however in order to find the relevant angles you'll have to work out some angles.
