when it comes to tutorials, is there a problem enrolling into ones that are back to back with each other ie. one goes from 8:30-9:30 and then another from 9:30-10:30 and then from 10:30-11:30 or should i try and space them out?
No, there's no real problem with doing that. Some courses you may have an in class test, so three of those back to back wouldn't be great. Also, while lectures usually finish early, a lot of tutorials run right to the end. So you may have to learn a few minutes early. However, for the most part, you'd be fine.
