I have a year gap between my 10th and 12th. Will I get a call from top IIMs if a score a decent percentile in CAT 2018?
All your marks like Xth, XIIth, Graduation shall be counted.
Year gap dont matter much. You can justify your gaps while interviews.
Overall you need to score above 99 percentile in CAT and 700+ in GMAT for top 3 IIMs.
Strong profiles alwags get calls with excellent academic performance and work experience.
