Eligibility criteria for appearing in XAT to seek admission in XLRI is a recognised Bachelor's degree of minimum three years duration or equivalent in any discipline. Those students who are completing their final examination by June in the year of start of MBA degree at XLRI are also eligible to appear for XAT.

RVS is a better option but to know the exact scenario for faculty and placements, you can get in touch with the current students through social media or in person.

680 is a very good score, but you have less chances as they call at 700+ scores for GMAT. Fees for two years is around 17 lakhs.

if you want to do b.tech in cse branch you need to study one more year and try to score good marks in JEE main and advance so that you can able to get admission in IIT, nit and bit , because cse from a good college matters in your career building prospects . rvs college Jamshedpur is a common college , I don't think it offers you a quality education and good job package.

NIT is the best college, but if you are not able to clear JEE then RVSIT is an opportunity for you.
