Hi, mahesh.

If you're choosing between any government college and private college please try to choose the government colleges, because you'll have the benefit of the colleges experience.

Now comparing srm Chennai and IHM trivandrum both are good colleges, but IHM trivandrum has better faculty, infrastructure, course curriculum and placement packages

So you can certainly choose IHM trivandrum
