One more reason to skip uni. Remote only experience for full price with orwelian nightmare included. All documentation and lessons are online for free. You do not need human text to speech engine that costs 30k/year.
Not all lecturers welcome questions, it depends on the country and culture. Certainly my own undergraduate experience consisted of a "human text-to-speech engine" experience where the lecturer lectured mainly from a text, while students were expected to silently listen, and then answer any questions they had themselves by searching in the literature.
When I moved on to graduate studies and had a weekly seminar, then questions and discussion were welcome, but I sympathize with the feeling that in-person undergraduate education is a waste of time and (in countries that charge tuition fees) money.
If you're in any other engineering field (EE, ME, etc), you're really not going to get a job without a degree. Compared to programming, it's like perhaps a 1% chance.
They absolutely are not pointless for software engineering. I tried skipping university and there is a night and day difference in responses before and after graduating.
So you don't need to ask any questions, ever? Then go to the library instead.
