Colleges in Rajasthan

Following are the non software fields with good scope in the future -
1. Network Admin
2. System Admin
3. Database Admin
4. Technical support for a product
Point 4 must be avoided if possible. Rest are good jobs. But its hard to grow if you hate or don't know programming.

It's around Rs 6.5 lakhs including hostel, mess, etc.

Both the institutes are good if you can work hard. If your basics are clear, then opt for TIME. You can definitely crack CAT exam with the help of guidance provided by TIME.

Networks Era is best for CCIE course.

You are requested to confirm your stream ( Science PCM/PCB, Humanities, Commerce etc) for appropriate advice.

If I would rank these two colleges (MNIT and MNNIT) on the basis of campus, hostel life, placements, faculty, and infrastructure, then I would suggest you MNNIT.
As for MNNIT - Allahabad, from what I know from my friends who went there, it's great for someone interested in the core branch as well as the teachers being so supportive for someone pursuing his/her passions.

What is your caste? JEE main ranks also depends upon category.

You will be able to get a teaching job in an engineering college based on your M.Tech, but you need to pursue Ph.D for your career growth.
