All-in-all, pretty easy. I know there are only two marks I have lost (The "express y in terms of x" log question; I did something very stupid because I was running out of time)
I may have lost other marks for not being precise enough or by making stupid errors somewhere along the line.
Still, I'm fairly confident that I have at least 94%. I may even have 98%.
Stats and Mechanics is a lot less predictable than Pure, so I may lose a few marks in Friday's exam, but I'm hoping that it will go well. I just need to be able to finish it in time.
