I think this is consistent with most universities, including what went on at mine (UWE).
You’ll be taught everything in terms 1 and 2 and have your exams in term 3. The only times this may vary is when you do your Masters course where you will still be doing your project until May/June (I was doing my lab project until the end of May) with the hand in date in July with your results in September.
You may also have any additional retakes during this time (coursework or exams) taken earlier in the year. Term 3 is more for assessments than anything, meaning most staff take their annual leave during this time.
