There are primarily three major factors that determine whether a college is good or bad. These include - facilities, placements, and faculty. Let me provide you a brief insight about it, which might help you understand it a bit better.

Placements:JSS provides good industry exposure. The location of JSS is also pretty convenient as it enables access to places near and far.
