Hello Flemy,

As considering you have a decent composite score in MAT, but your percentile is comparatively less. You must check three parameters before joining any institution; the parameters are a) Placement, b) Faculty and c) infrastructure. I can suggest some colleges because my friends and cousins are either studying there or have passed out.

NIT, Warangal - This institute on of the top Government Institute for MBA. Institute has a good placement record. Faculties are well experienced in teaching some of them has industrial experience also.
Lovely Professional University - One of my friends is passed out from here in 2016, now he is working with an MNC as a state head of their sales. Their last year placement also good, the highest package was 21 LPA.  Recently Amazon hired few students at a package of 28 LPA. Fortunately, I have the link so sharing with you.

You can read it yourself for a better understanding. LPU has its own test, LPUNEST (National Entrance and Scholarship Test) and this may help you to get eligibility and scholarship also if you are scoring well.
