Thank You, even though I still don't understand it haha. Does that mean I am horrific at maths, or that my maths foundation is wack?
No, not at all! What about it don't you understand? Is it the coefficient part?
3. I'm feeling so nervous tomorrow even though im getting average of 67/75. Is anyone else feeling the same?

BTW I hope everyone does really well tomorrow!

I feel the same way. Although I did that online paper that someone put in the comments and a) it was slightly difficult, and b) the site crashed and didn't save on the last question.

Best of luck to everyone.
7. btw guys, there's a really cool app called 'photomath' you just hover your camera over any equation and it tells you the answer.

Yeah that is the bit I am confused about. How the x^3/2 just went away? And how it became 2SquarerootC/3 = 4/3. Thank you for your patience!

Haha that's no problem at all! I've gone through the whole of what coefficients are as I'm not sure how much detail you know already.

Hopefully this makes more sense!
