    Mathematics: Post your doubts here!

    (i) The possible values of Y are 0,2,4. Calculating probabilities, P(X=0) = 0.5*0.5 + 0.4*0.4 + 0.1*0.1 = 0.42 P(X=2) = 2*(0.5*0.4) + 2*(0.4*0.1) = 0.48 P(X=4) = 2(0.5*0.1) = 0.10 Draw a table and put the values of y and P(Y=y) accordingly. (ii) Expected value = 0*0.42 + 2*0.48 + 4*0.10 = 1.36

    The lengths will be used to calculate the angle between the weight (vertically downward from P) and the tension force in string PA. AND, the angle between the weight (vertically downward from P) and the tension force in string PB. These will equate to 36.9 deg. and 67.4 deg. respectively. Then...

    Yes. Are you sure that recursion with stacks is even in the syllabus? Because, I've done the entire stacks structure with addition, deletion, etc. And I've done recursive functions too, in VB6, but I haven't come across recursion with stacks, yet. Recursion with stacks may only be used when...

    Look, if you're confident about the chapters and the methods, don't. I did it because I had to (school/teacher). Very little chances, I don't know. They haven't announced them yet. In Chemistry, yes. In Physics, no.

    A distinction can be achieved by someone who does as few as 2 years worth of past papers and not achieved by someone who practices the entire Classified. Getting 100% involves luck and concentration. I was hoping for one in Chemistry, though I messed up one 3 mark part (again, a silly mistake)...

    I didn't recheck THAT particular question, I had 10 minutes for rechecking so I skipped the first two questions (since I thought I couldn't possible do them wrong) and turns out I did a mistake in them. Just my luck. I solved Classified, the whole book.

    Exactly. No matter how many you solve, you're bound to make a silly mistake if it's not your day. The same happened with me, I practiced every single paper, made the silliest of mistakes on paper day.

    Physics: Post your doubts here!

    Solution: Assuming the table to be a smooth surface (frictionless). Loss in Gravitational Potential Energy = Gain in Kinetic Energy Loss in G.P.E. = K.E. of mass + K.E. of trolley 0.5*9.8*1 = 0.5(0.5)(v)^2 + 0.5(1.5)(v)^2 0.25v^2 + 0.75v^2 = 4.9 v^2 = 4.9 Considering trolley, K.E. =...

    So, practice past papers until you're good enough and confident enough to do any question. Then, it's just about how well you concentrate and pull it off on exam day.

    There's no secret. :P If you're aiming for 100% then there is the element of luck AND concentration. I had a near perfect Maths paper except that I made a mistake in FACTORIZING, I factorized 68 instead of 78 (I know, that luck). It was the only mistake I made in both papers combined.

    Computers & ICT: Post your doubts here!

    You can EASILY get an A. You already know programming to a great extent so you won't have much of a problem at all. The only thing you'll need to practice more is paper 2, if you can solve it then you'll get an A easily. P1 is completely O'level Computers except a few new things (such as single...

    PHYSICS ATP TIPS, EXPERIMENTS AND FEQs

    Faulty instruments, low precision, various errors, faulty experimental techniques. We only WROTE this in ATP exams, now we experience it.
