What was Question 3??
What were the questions 3 all of 6, 10, 11, 21 and 22 can't remember...
What would i have got for the last one if i put 40.1, as i read the question to be find the angle through using the 1/2 x A x B x Sin C formula.

And for 18a what would i get for putting - 10a^4b^3

For 17 if i wrote 30.1 without any workings what would i get?


You would probably drop 2 marks. How did you get there with not writing working? Easy marks lost.

1 or 2 marks for last question
Probably zero for 18 a
The marks, if last one is worth six, add up to 102.

3 at the most unless the examiner is very generous which is unlikely, especially for Maths. I'm not an examiner though so don't stress :smile:
~ Well, I know that I got at least half the method marks :tongue: ~
What was 12?
