Hm. For my differential equation, I went further and took one of the Ys to the other side :/ to get 4x^2/12-3y=y. Think I'll lose all the marks for that? :/ other than that full marks
I did exactly same as you but i don't think we should lose any mark since it is still same answer but just in different form. We also shown the answer in unofficial mark scheme somewhere during our working out. It should be perfectly fine, they shouldn't take away mark for going even further
Really annoyed with myself, did everything right in the last part of the last question apart from making a stupid mistake (I expanded the brackets and got 4lambda = 24) this may have cost me the a* :'( how many marks would I lose for this?

Arghhhhhhhhhhh!!!! I got y = 3x instead of y = 3/x by mistake.... got some stupid answer... how many marks am I going to loose? And pleaaase, what raw marks do you reckon you'd need for 82 UMS?? Think my A* s just gone, soo many silly mistakes gutted!
Haiyya, my calculations for the last bit are rift except I got lambda equals -7, so my final answer was wrong.. Also, I got y=
+-Root(9/4)but I substituted y=9/4 instead of 3/2by mistake :'( how many lost is that in total?
