    Not right now, no. 5 weeks is plenty. If you're still getting B's in past papers a few days before the exam, maybe then you should be worried.

    Apparently the exams are getting harder every time though, so I'd recommend doing some more challenging questions. Solomon papers etc.

    solomon c4 are easy though, c3 make me want to cry :'(

    I know they are :/ Jan c3 paper is crazily hard! :/ urgh trig!

    But then C2 in Jan was really easy, so its abit unpredictable really.

    What are the chances of normal distribution coming up on S1 (Edexcel) Friday?
    It will definitely be there, it's a whole section in the course after all. :rolleyes:

    The number of normal distribution questions on an S1 paper models itself in a normal distribution with a mean of 1 and a standard deviation of 0.0000001...

    Then you could try doing AEA papers or something, I don't really bother with Solomons anymore so I wouldn't know about whether they're harder than the real past papers or not. You could try Elmwood papers too.

    The kicker: after rigorous hypothesis testing, it actually models itself in a poisson distribution with a mean of 1.2.

    Why did you not just say: \ P(1q+ \ on  \ Normal  \ Distribution) =1 and be done?

    Since you're at the top of the special helpers list I thought I'd address this to you. For S1 Normal Distribution after you've found out the mean and SD, would you use your rounded or un-rounded values?

    What overall grade you need?

    My C4 mark didn't bother me, so I left it as it is.
    I assume you mean for my offer? An A but I got an A*

    Yeah I mean 79/100 is a good score for C4 so there's no need to stress with it What do you need for maths?

    I don't think you would (That said, I'm not 100% sure) but I would play it safe and use the unrounded value. Besides, doesn't the loss of accuracy of a rounded value make your skin crawl anyway? :lol:

    I know what you mean, it makes me cringe whenever my friends use rounded values for further calculations

    Yeah because you're using inaccurate numbers in the calculation so I believe you do lose marks. In general, you should not round at all until right at the end, and then round to the required number of significant figures.

    Ahh don't get me started... with the amount of times I've had to deal with approximations in Mechanics with subsequent parts of the question following on, life would be so much easier if everything just had an answer...

    Mehh, I just don't understand it. I don't get why you use all the formula and the questions are so wordy. Maybe it's just because I haven't done it before but I still don't like it :cry:
