I don't want to jinx anything lol - but I was really happy with the paper, and didn't think any of the questions were too hard. I was able to answer everything and felt like all my work was correct, with 5 mins to spare at the end to check through.
So overall, I'm relieved, because I resat the paper today after getting a B in the C12 June 2018 exam. I actually bothered to study this time... I guess preparation really does help haha.

Hope you guys feel good about the exam too!

Well, in the question (don't remember what number) about y = 1 + cosx...
I drew the graph as a regular cos graph, but with y values that went from +2 to 0, instead of +1 to -1
And for the second part of the question, using the trapezium rule, I got an area of 2π

If you can tell me what some of the other questions were, maybe I can remember my answers... but I cant think of anything else right now sorry
