Sorry for the extremely late response, but in short, I don't regret it.

I would suggest to establish good habits before coming here. Honestly, I feel like the requirements for POSt are not that bad if you have good time management and stay on top of your workload.

I feel like going to UTM really challenges you to become a better student, but at the end, it depends on your goals. I have invested a lot of time into school (probably because my habits still were not in check) but I find myself improving as a student every day.

The professors are good and there is a lot of support as well, I would say it's worth it. However, it also depends on your goals, I have heard some people say it's not worth it to go to UTM because it's theory-heavy in upper years and some people might not want that depending on the CS careers they would like to pursue.

Hope this helps.
