You should absolutely prepare for the GMAT and aim for a strong one‐year MBA in India. Your 6+ years in M&A tax/legal with 15+ deals at Big6s is a rare, high‐value profile that schools like ISB, IIM PGPX, XLRI PGDM‐GM, SPJIMR and MDI will pay attention to, even if your academic scores are average.
For admissions, your GMAT becomes critical to offset grades. For ISB and IIM PGPX, realistic chances start around 700–720 (Classic) / 665–680 (Focus); for XLRI‐GM, MDI‐BM and SPJIMR‐GM, you can be competitive with 670–700 if your experience and essays are sharply positioned. Your 550 in a 7‐day mock means a 700‐range score is achievable with 3–4 focused months of structured prep and 2–3 retakes.
To strengthen your case, frame your experience around “transaction strategy”:
Highlight deal value, cross‐border structure, tax‐legal trade‐offs, and client‐facing decision impact (not just volume).
Position your CS + LLB + 6 years M&A as a regulatory‐strategy bridge, which fits perfectly with a move into M&A consulting - corporate development / corporate strategy post‐MBA.
If your best‐expected GMAT ends up under 670 (Focus) / 680 (Classic), target XLRI PGDM‐GM, MDI‐BM and SPJIMR‐GM as realistic India options; ISB and top‐league PGPX will become stretch targets. For international backup, consider mid‐tier European schools like IESM Strasbourg, Rotterdam‐IMM, Frankfurt School or Leeds/Lancaster/Bayes, which often accept solid profiles with sub‐700 scores.
