Actually, there is no such thing as academic weightage in FMS, but MDI gives academics weightage. To get a call from MDI, you must score higher than 98.2x for FMS and 95.5x percentile.
FMS is part of Delhi University, and its tuition is significantly lower than that of MDI. FMS fees are around 20-21k, whereas MDI fees are around 28 lakhs, which is much higher than FMS. FMS and MDI both give sectional cutoff weightage. If your academics are strong, it will benefit MDI, but FMS does not give academics weightage.GDPI considers extracurricular activities, work experience, and any other achievement.
