In VIT-Pune, there is no lateral entry for MCA course unlike in engineering courses.
All the best!

Basically, government colleges are not so updated. So, their placement (campusing) & class quality not so good as like private colleges because there are lots of Politics. But, in maximum private colleges there fee is quite high/expensive. But, now, you get all those benefits under Singhania University. 100% placement with the cheapest course fees.
