can all of you taking physics tell me how you are studying for the paper 6. what topics are you revising and how are you revising? (for example are you just doing past papers or other things as well). I'm in some mess, and i' trying to get out of it.
Thanks

dont worry about physics its really easy u will realise that once u start doing lots of p6's :P
atm im only doing past papers but im focusing all little more on mirrors /rays and circuits cuz some are hard, some of them are also included in p3.

u mean other exams or topics ?

well i dont study as much p6's for physics as other exams cuz its not tht hard.

other p6 topics are easy, most of the questions already have an equation and u basically put numbers in them to get an answer, and some questions they tell u to measure X-Y etc using a ruler :P

Solving past papers and knowing all the ideas in them are all what we need.

MJ03 b)i) c=1.2*3.142
=3.77 mm=0.37cm
ii) 90 degree -> 0.37
   360 degree-> x
x= (using cross multplication) 1.48cm

sweetsh i think ur answer is wrong .. we should devide 3.77mm by 4 which gives us 0.94 mm

you have to divide it by four because it says that the pointer moved through to 90o. And 900 is 1/4 of the pin's circumference.
