Between 50 and 60.
Unfortunately, as we got out some people were worried they might have only gotten 30. The first question threw a lot of people off as it wasn't as easy as the previous year's tests we'd been practising. I guess they must have figured that since everyone was getting some of those easy questions, like dividing the interval*, and limit x to zero of sinx over x* right, they could probably test for harder things.
*I do 4 unit, so I didn't pay much attention to the difference between 2 and three unit work because it simply didn't matter, these may be 2 unit skills though, I don't know.
