If you are taking written exams, you will usually complete these at the end of Trinity Term, during Week 9. You are expected to remain in Oxford until your examinations have finished. If you are completing an MPhil, you will take your Qualifying Examinations in Trinity Term of year one, and you will take a second option paper in year two. During the long (summer) vacation, you will undertake your MSc thesis research, either in Oxford or overseas (depending on your topic). You will need to submit this by 15th August. 

Examination Boards and results 

Examination Boards are generally held in early- or mid-July and mid- or end of September, and examination results are published as soon as possible after the examination board meetings. You should be available to return to Oxford if called back for a viva voce (an interview with the examiners, usually called if you are borderline between pass/fail or pass/distinction or, more rarely, where plagiarism is suspected).
