Hi Abhishek, it is not about these scores which matter in the CAT admissions. Most of the colleges just have a minimum eligblity criteria of around 60%+ in all exams. Actually your score is perfectly fine. All you need to is, concentrate of scoring high marks in CAT exam. It is all what matters and makes colleges give a call. Most of the colleges give less than 10% to even no weightage to the college and school marks. For older IIMs you woukd require above 95+ percentile and for new IIMs it is around 90+ and above 85+ for the newer IIMs for the newer IIMs in CAT exam.
