Hello,
Anxiety about packages at the time of placements is an activity, that every student has to undergo. But anxiety should spur you into doing better and not bogging you down.
Packages are strictly a function of demand & supply. Also, your academics. Employers surely will like to get best value for their money. Hence top packages are offered only to 1 or 2 students.
Presently, IT rules the roost & if you are in top five of your batch you can expect 6-10 L. Others would get about 3-5 L.

Thanks for your query. M.Tech through distance education is not deemed valid. We can help you to get admission in part-time M.Tech.

Depends on your marks and academic profile. Everyone has a chance. :)

You can pursue M.Tech after completing B.Tech if you have interest in technology. Or if you are getting a good job then you can go for it.
