Good Govt. colleges for PG in Karnataka

In the large South Indian of Karnataka, one would expect a lot of good govt. colleges however, the MAIN names that come to mind are:

NIMHANS [Central institute]

KMC, Manipal [private]

Bangalore Medical College

ESI, Bangalore

Could someone share the names of Good institutes in Karnataka And the Pros and cons of doing PG there?

Also, How tough is it to learn Kannada for outsiders?

Are the people welcoming towards/tolerate people who're just beginning to learn Kannada?

[NOTE: This post is not to demean the state of KARNATAKA in any manner, I have immense respect for my KANNADIGA colleagues, their culture and KANNADA language, and a lot of my friends in GMCGOA are from Karnataka who've settled in Goa].
