No, I am not doing any Statistics. I did not enjoy it too much during the Semester. In fact, I did not go to any lectures because I already had a plethora of resources. I've already done double/triple integrals. They are quite simple really. The application of it is not too difficult.
I tried looking at contour integrals (the integral sign with the circle in the middle) but it was a bit difficult to understand. I am also currently revising Linear Algebra.
How did you go in First Year uni? You need a HD average to do it in Second Year. Personally, I don't want to do it. Reason being, I want to do more Maths subjects that allow me to learn more things, rather than doing something only 3cp that just teaches you how to write in LaTeX, how to format your proofs etc.
