The entry requirements for a combined MS and PhD programme is similar to that of a Doctorate, as most applicants for the combined programme would not have an advanced degree or journal publications. Admission to a combined degree can also be very competitive with most universities accepting just 3-4 candidates in a session.

Factors regarding PhD after Bachelors admission:

1.  Strong GPA - Candidates need to have excellent Grade Point Average to qualify for the programmes. Students from other boards can find the equivalent to the GPA to assess their eligibility.

2.  Standardised test scores - Candidates have to score very high points in the standardized scores. Here the student will be asked to submit test scores.

GRE: GRE is mandatory for almost all PhD programmes, including management studies, after Bachelors in the USA. In case of doctoral programmes, most students are required to present GRE subject scores of the course as well

GMAT: GMAT is taken for admission to management studies. Business schools offering PhD in business management accept GMAT score for admission into a wide range of PhD programs in management.
