A 77% in 10th with 94.5% in 12th and GNEF (General Non-Engineer Female) profile gets full IIM ABC calls at 98.5+ CAT percentile because the combined diversity bonuses compensate for the weak 10th.
At IIM ABC, the female + non-engineer + good UG acads combination typically gets 5-7 percentile effective cushion. Your 77% in 10th costs you 4 points vs a 90%+ candidate at IIM A (6 vs 10), but gender diversity (+2 at A, +5 at B, +4 at C) and non-engineer diversity (+5 effective percentile at shortlisting) more than offset. The AMA commenter correctly said "Very high, aim for 98.
5+ percentile, all the calls will be available to you." At IIM Ahmedabad (Rs 27.5L fees, Rs 35.
22 LPA avg, 99%+ CAT cutoff), a GNEF at 98.5 CAT is roughly equivalent to a general engineer male at 99.5 in effective shortlisting chances.
10 months work-ex is a slight bonus (typically 1-3 points at IIM B which weights work-ex most). For IIM C specifically, your strong 12th (94.5%) gets you 13 points (of 15 max), and the 77% in 10th only costs 4 points in a 10-point weighted metric.
Interview performance becomes critical - as a GNEF you'll face probing on your UG choice and career motivation. IIM Lucknow (Rs 22L fees, Rs 32.3 LPA avg, 97%+ cutoff) and IIM K are even easier targets.
Don't underestimate your profile strength - GNEF at 98+ is a premium category at most IIMs. Check your eligibility at collvera.
