Are we allowed to complete say 3 or 5 units in a semester? Or is it typically 4 with exceptions.
The standard full time academic work load is 24 credit points. This translates into 4 units per semester assuming 6 credit points per unit, which is the case for the majority of units.
Doing less than 4 units is referred to as under loading and this is possible for courses that allow part time study. There are other considerations when under loading such as when a particular unit you are planning to take is run next. Considerations when picking units tend to be specific to each studentís circumstances and the course they are enrolled in. For this reason it is advisable to talk to your course coordinator who will be able to provide more specific advice.
Doing more than 4 units is referred as overloading and this is not generally allowed. The some cases overloading is only permitted after seeking special permission from your faculty. Your academic average among other things will be used to determine if you will be able to cope with the additional load.
