There are two ways to look at "difficult".

1. Time required.
2. Actual difficulty in learning.

I had one course, which was essentially history of computing. covered everything from egyptian numerals to how the modern processor works (von neumann architecture). the material wasn't hard - but the amount of homework and effort that was required to obtain very little marks (eg: reading 70 pages and writing a 750? word summary) was worth about 0.40% of our final grade. Each week we had to complete 10-12 tasks like this for 2% of our grade. The major assessment pieces weren't much better.

I feel like every CS professor is like that. I figured I was done writing papers after English classes were done with but I'm pretty sure I wrote 10x more papers in CS classes and way more frequently. And they were longer and required more research, LOL.

The other course - was on Cryptography. That was probably the most difficult course to actually complete as far as intellectually difficult. I was never great at mathematics. this course just proved it lol They actually had us writing out and working with cryptographic algorithms on paper :/

That sounds very painful, especially without a solid math background.
