MAT

Hi Akanksha,
You have to take the IELTS for English language requirements. There could be other tests such as SAT or ACT etc. depending on where and what you are planning to study.

Yes, you have a chance for MET/IES.

Yes, you are eligible for admission to Galgotias University. You need to contact the university in person and get admission. You can also go for direct admission there.

If you want to pursue MBA from a reputed college, you should prepare yourself for the entrance exams conducted for the same. Reputed B-schools look into your CAT and other similar exam's percentile and give you admission on the basis of it. Other colleges make it mandatory for you to score at least 50% of your graduation degree to grant you admission in MBA.

Kindly rephrase your question.

Yes, you've got decent chances.
All the best.

You can look for BIMM-Pune, IPE-Hyderabad, NIT-Warangal. Check the below link for colleges accepting MAT score-

Yes, admission can be taken based on MAT score. DTE assigns rank based on your MAT score and admission is based on that rank.

50% is the safe line as many core finance job profile demands 55 or 60% and some domain marketing FMCG or market research firm demands 50 percent. It is the bitter truth that you can't have the best colleges or even the good colleges as the entrance test criteria is 50%.
But you can have a better future. Achieve 3 or 4 years of job experience and join the executive MBA from top colleges. But do not try to get colleges through management quota as you can't get a good college this way.
