Does past graduate work affect your application for PhD programs at Oxford and Cambridge?

Will strong work in a Master’s program compensate for a solid (but not immaculate) undergraduate GPA (US grading)? What is the equivalent minimum US GPA required for a successful application? Would strong work in a doctoral program assist in applying to do additional postgraduate work?

1. Maybe.
2. The minimum GPA would depend on the strength of the rest of your application.
3. Definitely.
