Navigating undergraduate admissions in India with international qualifications often brings up a major point of confusion for students and parents: the conversion of letter grades into numerical percentages. Since most local university cut-off lists and merit frameworks are built entirely around raw percentage scores, calculating an accurate equivalence is vital. The standard practice relies heavily on the Percentage Uniform Mark (PUM) provided on the official Cambridge Statement of Results, which maps letter grades directly onto a standardized 100-point scale. However, operational variations across state universities, autonomous colleges, and central institutions frequently lead to differing internal calculations and admission criteria. This forum space is dedicated to sharing firsthand application experiences, formal university policies, and practical insights on how different Indian higher education institutions process these international scorecards to determine final merit ranks.
