    Basic? I don't get you. :confused: If it was NaSO4 + KCl, then the reaction would have happened, double displacement, KSO4 and NaCl would have formed. They are both salts, the more reactive element will displace the less reactive element.

    Maths, Addmaths and Statistics: Post your doubts here!

    I agree with falcon678 here, Add.maths is the maths of A'levels (simplified), that's why it is important for engineering students to take it. Maths and Add.maths only seem hard if you lack practice. Practice does wonders in ANY subject, so it's all about determination.

    Lol, not for me. Maths doesn't have relative velocity, integration or permutation (which attract mistakes). Maths just needs to be done sensibly!

    As far as I know, bearings are always 3 digit, for e.g. 070 degree, 275 degree. All other angles are to 1 decimal point and all other numbers are to 3 significant figures.

    I do the same, I'm just eager to give the paper away.

    Well, to be honest, I usually complete the paper with 15-20 minutes remaining. That means I can check my paper and go through the answers and search for mistakes (but in school and mocks I slack off and don't do it), so yeah, 100% can be achieved.

    Its good that you actually know what f' means. One of my seniors did a mistake with this last year.

    The question says that it is a factor of f' and f not f inv. and f. There is a difference in both of them. f' is the differential of f. f inv. is the inverse of f.

    You didn't read the question, did you? ;) It's f' not f inv. :)

    how many of you study just few hours before the exam!

    I agree, it's not like you're going to get all the concepts and theories in one night. The understanding develops with time. Rattafying the things won't take you anywhere in sciences.

    Lol. People don't know that we don't discuss maths. Spare them. :D Me and Suchal only discuss Add.maths. Maths is too easy. :p

    Notes? Well, I won't change. I'm used to people like that :p There is no harm in helping people. Idiots are to be found everywhere (who make fun of others), just ignore them.

    I'm not telling you to worry. :eek: I'm saying that you should not be surprised by the fact that even CIE makes mistakes.

    Yeah, but I was referring to the fact that you were surprised when I said that 'CIE has made a mistake'.
