What did people get for the equation of the line through the mid point of AB?

6x+4y-29?? Something like that... Might be the wrong question..? Sorry...

K<-25/8

Below the vertex

Dammit, I put that but convinced myself out of it

Is it possible to get an A overall if I get a B in c1 a high A in c2 and an A in stats?

I also got stretch sf 1/3 parallel to the x axis

What did everyone get for the last indices question? I feel like I messed it up!

Also, answers for the differentiate X^(1/3) where X=8 or something?

yeah you just need 240 ums overall. you could get a C and two A's and still get an A

Has to be tin the form "5^k"

Few questions. 1) is parallel to the x axis same as in the x direction
2) how many marks will is loose for writing (5root5)^3=5^11/2
3) for the area I worked out a y coordinate wrong therefore my area was wrong. How many marks will I lose.

I got 5^4.5 for the last indices question

What expansion did people get for simultaneous equations. The rest was a breeze however I spent a good 30 min + solving :

3x^2 + 20x - 22 = 0

As y=-2x-5 so I just substituted. I think I got it completely wrong but I tried 5 different ways and came to the same expansion which I couldn't simplify...

Really hope grade boundaries are not higher than last year :/

It had to be in the form 5 to the power something, I got 5^(9/2)

what did people get for a on question 9i (i think)???

Would it not be 5^4 x 5^1/2??

i got 1/12... probably got that wrong

Has MR M / K stopped doing them?

I don't use TSR much, does he do them for OCR A level? I just remember him doing them at GCSE for edexcel.

and what did everyone get for 10iii???????? area of PQR

I got something like -3/16, I think I did it wrong
