Exam

No, admissions in School of Management Studies, MNNIT are done only through CAT (conducted by IIMs) followed by GD and Personal Interview.

You are eligible for Bachelors studies. You will find that in Germany medium of instruction is German for Bachelors programme.

You will get scholarships according to your SAT marks for undergraduate course in the US but if not, costs are pretty high.

No, that is not right. What is required is that you need to be at least a graduate from an authorized / approved university and must have overall at least 50 percent marks in graduation.

Not a bad idea at all. Infact MBA through regular mode of education would be very good if you can leave your job for a period of 2 years. Here you have the option to do MBA through Part-time mode or distance mode, which will not require you to appear in CAT / MAT.

There is no definite answer to your questions. Difficulty does not have levels. If you can understand something in education then it is not difficult otherwise everything is difficult. So better focus on what you study and learn it perfectly so that you can enjoy your education.

Yes, you can take admission based on MAT exam, but it depends on the college you are applying for because, some colleges accept MAT scores while some don't.
