Do Class 10 and 12 Marks Matter for IIM Eligibility?
Yes, they absolutely do. Most of the students associate the CAT exam as the entry to the prestigious Indian Institutes of Management (IIMs). Scoring a 99+ percentile in CAT exam is not a simple thing, it requires months of rigorous preparation and dedication. But here’s the lesser discussed reality that an excellent CAT score alone does not guarantee a call from IIM Ahmedabad, Bangalore, or Calcutta but the academic profile do matter.
