M1 Maths, Edexcel

* Make sure you draw diagrams properly so that the examiner can understand
* DIRECTIONS are important in some questions, make sure you state which direction you are using to the examiner and get your signs right!
* Answer the question that you are being asked and not the one you are NOT or going to be asked!
* Unless otherwise stated, do not do accurate answers, actually work out the g value, or the square root and put to 3 sig fig unless otherwise stated

THANKS .

Do you reckon the paper is gonna easier or harder than the Jan 2010 one.

Jan 2010 was fairly easier..

I am not sure

in Jan 09, grade boundary for A is 49/75 (raw mark)
in Jun 09 it was 55/75
in Jan 10 it's 61/75

do you think this time it will be 67? (because 49 + 6 = 55, 55 + 6 = 61)
when I saw it, I just laugh after realising this

Tbh, I guess this year it will be harder (it just can't get easier and easier all the time) and the grade boundary will be lower

Good luck with your exams!!!

Yeah you might be right!

Hopefully, it will be in the around 55 to 60 marks for an A.

With no big Vectors questions coming up! I do hate vectors!

ermmmm.....can someone help me in moments, i dont really understand how your suppose to know if the particle is rotating clockwise or anticlockwise????
really confusing me :/

After taking moments about a point:

Right hand side:
Force acting upwards will move clockwise
Force acting downwards will move counter clockwise

Left hand side:
Force acting upwards will move counter clockwise
Force acting downwards will move clockwise

It works just like a clock, hope this helps ^_^

Why do I have a horrible feeling that it's going to be the hardest M1 paper so far?

3. When finding the shortest distance between 2 position vectors at time t or whatever, it's quicker & easier (i think) to differentiate (using chain rule or implicitly) than to multiply out & complete square
