I have just finished my 1st year at university studying Computer Science (I wanted to be a Computer Science researcher, now I'm not that sure), but I barely learned any Mathematics (I didn't even learn Calculus nor Linear Algebra in this top 10 UK uni...). This has been so striking to me that I am considering changing to another program such as Mathematics or Physics, but I don't know if I should. Maybe the 1st year at university is intended to be easy (too easy), and it will get more mathematical with course units such as Machine Learning. But it does make me sad that if I continue in Computer Science I won't learn more Mathematics such as Real Analysis nor will I be exposed to abstract ideas. I have been thinking about it for months and haven't still made up my mind. What should I do?
