I study both mathematics and computer science at Delft university. There's a difference between the approaches these two studies have.
Mathematics is usually about going to lectures, learning complicated stuff there and then using the obtained knowledge in a exam at the end of the course.
The CS courses are kore about engineering. They have practicals way more often than the math courses and the exams usually are of les importance.

It feels as if the "academic level" of the CS courses is lower. In math, we learn the real deep, abstract matter, while CS is more about "tinker up something nice in the practicals and you'll be fine."

I'm not sure if either approach is better, but I'm sure I like the maths version more. The CS approach is more HBO-like (HBO being the lower-level universities)
It is even that, generally speaking, the people who study maths seem more serious about studying than the cs people.
Not all of them, and no offense meant, just an observation.

Well, that was not really a rant. If you read up to here, I'm curious what you think about this.
