i got 73 i think, it was confusing at first because you had to realize it wasnt an AP or a GP, you just had to add them all up in the end

Phew those papers were too good to be true! I messed up with a few stupid mistakes, like an idiot, but should get method marks and just lose accuracy marks.

For the tan question i got tan(angle)=1/5 (i'm really bad at those questions and was so lucky it was only a few marks), but do you think i will get marks in part b) because i followed through, but with the wrong answer??

Grr i made a few dumb errors

Does anyone know when the marks scheme will come up? (not the offical edexcel one but the other one)

Now for M1 to mess up...

log6 36 was the best question

I didnt get the n= thingy and the last question I did the wrong calculations but other than that I think i got the rest ok.

By the sounds of it theres gonna be a lot of 90+% on this forum...

Good to hear that most of us are expecting good marks, btw what was the answer to the last question. Area of PQR, i got something like root 125 * root 65 * 1/2

The way i did it was to plot the graph, find PQ and PR the use the formula 1/2bh because i couldnt remember the sin formula for area.

thanks

plot the graph with the points (0,10) (-1,2) (11,8), the formula was 1/2 BH as you cant use sin formula and stuff without a calculator. work out the lengths of lines (-1,2)(0,10) and (0,10)(11,8) and then multiply it all up
et voila
