I am scoring 34 in cracku XAT mocks . Can I get XLRI call?

Score the same on D-Day and the answer is yes

NMAT OA-247 QA-73 LR-78 LS-96 Is it safe for NMIMS Mumbai?

QA and LR could cause issue. Retake, QA target 75+ and LR 80 +

I am unable to login on NMIMS using my GMAC ID, as it shows "invalid credentials". is this happening to anyone else?

I also faced the same issue yesterday.But I have a plan that might work.Atleast I followed the plan.Raise a query ticket(link available on that credentials requiring page) and also email nmims mumbai regarding this issue in their admission related email(available in their homepage bottom)(do both these tasks through your email id registered in nmat).Please also mention other many students are also facing the same issue.The more students report this same issue to them,better are the chanes they will take it seriously(i think so).Its written that they will revert back in 72 hours.Also try to reach them by call in their office hours(can avoid saturday,sunday) to report the issue.
