CAT

You have a very fair chance in PGDM-IB which runs parallel to PGDM.

Last year, the cut-off was 70 and hence, you have fair chance of getting admission, if you perform well in WAT/PI process.

Yes, you can apply in this college but it also depends on the performance of your group discussion and personal interview .
Hope this solves your query.
Thank you.

Please write all your marks in details.

Since MBA is a masters degree, a bachelors degree is a prerequisite for studying at IIMs. Other than that you need to clear the bare minimum cutoffs of colleges which vary from institute to institute. Scores for IIMs vary from year to year. But a score above 97 percentile will get you calls from atleast new IIM's. The higher the percentile the better.
All the best!

You are eligible to appear for CAT but after that you will get calls from IIMs based on your percentile and considering all other criteria, so at that time they will look at your academic profile.

No, XISS don't have NC-OBC reservation and yes, you are eligible for HRM as per last year cutoff. So, fill up the form and wait. All the best!

You have a decent percentile. NPTI is a good institute but it won't boost your profile. NPTI students have got 100% placements but their average package is 5.5 lakhs. It would be better to do energy management from a good business school.

Different colleges give different preferences, usually it varies between 10-25 percentage along with that your work experience may be given some preference.

You can try in Christ College, Bangalore. You should appear for MAT and PGCET exams in order to get concession in the fees. These exams are accepted only in Karnataka state. Don't lose hope.
