I got arrear in my Last semester in engineering Can I get admission in MBA.

Hello, You can get admission for MBA, only if you are able to clear the engineering arrear before the deadline mentioned by the college. Generally, the colleges specify a particular deadline within which all important documents like all mark sheets, degree certificate, etc. Have to be submitted.

You need to be a graduate to get admission into MBA, plus you need to have scored minimum 50% marks at the graduation exam. Thus you first need to complete your BE and ensure that you score overall more than 50% marks. Post this, you need to clear CAT with a high score to seek admission in a good MB

Well, arrear don't effect on your further studies as far as you pay them in time and for MBA you need to clear CAT, MAT or XAT or any other MBA entrance exams after your engineering. Good luck.
