The rankings are just out: top 100 engineering colleges and top 25 medical colleges. The cover story is here, and the methodology is described here. If you read the methodology, you will find good reasons to not take this entire ranking exercise too seriously. So there.
However, there are other interesting stories that accompany the Cover Story. One of them recounts the sad story of how the famed Karnataka model was undermined and destroyed. There are two articles by engineering graduates (and currently employed in IT industry) from private colleges in Tamil Nadu. While both of them (with a not so high grades and entrance marks) are grateful for the opportunity to study engineering, they are quite candid about the problems in the system of private colleges. From T.R. Muralidharan's article:
... Anna University (to which all engineering colleges are affiliated) is still finding it difficult to ensure that infrastructure and facilities at the colleges conform to standards. The quality of education rendered too is often substandard. There is a shortage of good professors in areas like IT and communications where developments happen rapidly.
Here's S. Senthil Kumar, a Dalit student who is now with Infosys:
Private engineering colleges in Tamil Nadu operate like small-scale businesses with disproportionately high turnover. Their marketability is determined by the numbers getting distinctions, the number of students going abroad for higher studies. Most of these colleges come up with bare minimum facilities, just about meeting AICTE requirements. Once revenues go up, more "facilities" are added. My college had a few good lecturers but many mediocre and not-so-good ones.
