How did your practical for v34 go? was it hard?
and no titration I heard?
Yes it went terrible, after all the great papers.. my total now on the border of A* and A, around 190/260 (considering a 30 in p1) :( i hope i ace p1 now.. but i find it hard to go above 32-33 in it. And yes no titration!

Very true I had the same thing, That's why you had to conduct separate test for it
It was NO3
