IMT is far better compared to Jaipuria. If you get a very good percentile in CAT above 80% percentile than IMT will call you for next process. Huge difference between both of the campus. In every aspect, IMT is one of the best campus in Delhi. Don't compare with jaipuria.

There is no such thing as sports quota in Christ University to the best of my knowledge, but excellence in sports will certainly add value and make your admission easy. Admission process remains same write the test, clear it and sit for personal interview during that time they will surely ask about you and your past achievements. You can always boost about your sports achievements, remember to carry certificates quota is when you have a cutoff for a course and BBA course have no cutoffs, you must have passing percentage in class 10th and class 11th and on that basis you can get admission.

No, it is not possible through distance.
