Hey just wanted to know whether people would recommend doing back-to-back units, for example an arts lecture from 1-2, and then another arts lecture or a tutorial from 2-3. Do lectures or tutorials tend to go overtime? Should I put an hour gap between each unit on the same day?
All classes are scheduled to start on the hour (e.g. 10:00am) and finish 10 mins to the hour (e.g. 10:50am). The 10 minutes is a buffer for students to get to their next class, so yes, there is enough time for you to get between classes.
You don't really need an hour gap - personally I find 1-hour breaks for private study are unproductive - by the time you've found a spot to sit and then open your laptop/books, you've only got 30-40 mins to pack up and head to your next class. However, I do find them useful for lunch, etc.
P.S. There are some people that do something like 5 hours of classes in a row to get them out of the way
