I didn't see any exam threads for S3, and I'm assuming a fair amount of people on TSR will be taking the exam, so I have made the thread for it!

I'm copying the resources Kevin De Bruyne shared when he made the S3 thread last year, hopefully he doesn't mind

Madasmaths - awesome website for loads of things for all of your exams, with a few topics that come up in S3.

PhysicsAndMathsTutor - link to loads of useful things.

FMSP revision page - some videos to watch about the specification and a specific set of exam questions.

Obviously I'm sitting the exam too! If anyone has any extra resources to share then that would be great. This is an easy exam as far as Further Maths go, so let's try to bank the full UMS

Any questions ask and I'll try to help (if others haven't answered already)

Zacken would you be up for helping with any questions? And will you be doing model solutions for the paper? Cheers.

Hey, this is an error in the question pack, part B is aimed at S4, as is part C. I think it is on the pack because part A is attainable.

Does anybody know why for the difference in two means formula in the formula book it says you do (X-Y) (as in X bar minus Y bar) rather than just small x bar - small y bar? because the latter is what you actually do in questions I'm pretty sure, you use the SPECIFIC sample mean rather than the sampling distribution mean

The modules are not as hard once you've done some papers. I would say M4 is the trickiest one.

I find M5 to be worse. Maybe it's the scarier number, haha, or the fact that I loathe all Mechanics, so everything seems terrible unless practiced, lol. Good luck with all of your exams!

Can anyone shed any light on this last question? I get that you can switch it to the fact (Xbar - mu) > 0.5 is 10% but then why does the equality flip again straight after?

Thanks

No that makes perfect sense. I was getting the z values the wrong way around. Thanks

My thoughts on this would be that because when it uses the capitals, it's illustrating the distribution rather than specific samples. Small ones refer to actual statistics whereas big ones refer to the variables themselves.
