Applying to Oxford for physics involves navigating a variety of colleges, each with their own strengths. While one user noted a friend's positive academic experience at Hartford, they also mentioned dissatisfaction with the overall experience. The discussion highlights a preference for Cambridge, particularly the Natural Sciences (NatSci) program, which allows for flexibility in module selection, including options for mathematics and computer science. It emphasizes that regardless of college choice at Cambridge, students attend the same lectures and have similar access to supervisors, making the college's reputation less critical. Instead, selecting a college based on personal preference, social atmosphere, and location is advised. Visiting colleges during open days or arranging tours can provide valuable insights into the best fit for prospective students.
