Over the years, IIMB has found that students who perform well in the academic programme are typically those who have a consistently good academic record at the school, high school and graduation level, and who exhibit a sufficiently high aptitude as measured by CAT (Common Admission Test of the IIMs)/GMAT. Therefore, IIMB uses these parameters to judge the suitability of candidates for the PGP programme. The admission process also includes a personal interview, conducted through remote video-conferencing for international students, and an assessment of writing ability. Relevant work experience, if any, is also given weightage.The CAT/GMAT score is also used to establish the minimum level of proficiency expected from a candidate in respective faculties as indicated by the section-wise minimum scores in the CAT/GMAT. Multiple criteria are used to arrive at a composite score for every candidate, which is used to select candidates at a subsequent stage.The cut-off for the CAT/GMAT score, one of the most important parameters, varies from year to year.
