An undergraduate course is an entry level course at university. Most of them are bachelors degrees (although there are some Diploma and Associate degree courses). Do don’t need to have studied at university before. Most students go from year 12, but you can also apply as a mature age student, or have done an enabling course or previous study at TAFE. You can also do an undergraduate course if you have already done a degree, but in a different field. In medicine, undergraduate courses are 5 or 6 years long.
