I'm on the OCR board, P3 is on Wednesday.
4. I do OCR MEI...i think its one of the hardest boards for maths
5. i thought the difference between OCR and OCR MEI is that the MEI version skips out stuff present in the OCR exams.....or is it the other way around....someone please enlighten me to the difference!
6. no idea...but ive got p3 the wednesday after next i think or somewhere around there
7. yeea that's right...same here...and assume you have m2 this wednesday (or s2 on friday or both)
8. yep s2 on friday...man i dont like s2 i did p1 too before half term on the monday
9. relax....just remember the important things. For some reason I always forget that expectation = Mean (except when using a sample of the parent population - then the mean may differ from the expectation)....am i right on that?
10. ye think so..i get really confused with the continuity correlation thingy watever its called...i never know whether to add 0.5 or take away 0.5
11. continuity correction factor when modelling discrete on normal distribution.

Just think upper and lower bounds...if you were finding probability of something being of value between 50 and 60, well that's actually 49.5 to 60.5 (because if you got any mark within that range, say, in an exam, your mark would be a whole number between 50 and 60). Of course that's assuming 50 and 60 inclusive....50 to 60 exclusive really means 51 to 59 inclusive. Then you just extend with your upper and lower bounds to 50.5 and 59.5

You just turn it into an inclusive boundary (rather than exclusive) and then make the range bigger by taking 0.5 from the lower one, and adding 0.5 to the upper one
12. cheers mate..that helped a lot im sorta gettin it now
