GPA (Grade Point Average) is a weighted average of all course grades, where each grade is multiplied by the course's credit hours before averaging. This weighting means a 4-credit STEM course has more than twice the GPA impact of a 1.5-credit elective. Understanding this is critical when deciding which courses to prioritize. A C+ in a 4-credit required course damages GPA far more than a B− in a 1-credit PE class.
Weighted vs. Unweighted GPA
Weighted GPA (5.0 scale for AP/IB courses) can create GPAs above 4.0. This rewards course rigor but makes cross-school comparison difficult. Most college admissions offices recalculate to an unweighted 4.0 scale for comparison. A 3.8 unweighted in rigorous courses is typically more competitive than a 4.2 weighted in easier courses.
GPA Thresholds for Different Paths
Medical school: minimum 3.0 overall/3.0 science; competitive applicants average 3.6+. Law school: top programs look for 3.7+ with LSAT carrying equal weight. MBA: top programs average 3.6, but work experience compensates. PhD: research experience weighs heavily alongside GPA. Employment: most companies with GPA filters use 3.0–3.5 minimum for early screening.
International GPA Comparisons
International GPA conversion is imprecise because grading philosophies differ. UK First Class Honours ≈ US 3.7+. India's 10-point CGPA: divide by 2.5 for approximate US 4.0 equivalent (9.0 CGPA ≈ 3.6 GPA). Germany's 5-point system inverts (1.0 = best), with 1.5 ≈ US 3.7. These are approximations — graduate admissions committees interpret international transcripts with experience.
