M.Tech Eligibility

Most of the institutes (All IITs, NITs, IISC & other reputed colleges) use GATE score for admissions in M. Tech programmes. Some institutes (Mostly IITs) have the provision of 30% of marks in BE/B. Tech in final allocations of seats.
In MNIT, GATE score is used for admission but min. 6.5 CGPA is required (due provisions for various categories).

However few institutes have their separate procedure for admission in M. Tech programmes. You can read about that in following link- http://www.inspirenignite.com/m-tech-admissions-2015-without-gate/

Hi Debashis
If you want to study abroad, you need to keep few things in your mind. Those are as follows…
1. Regarding where you can study - It has to be decided based on your interest, basic facilities, requirements, pocket and scholarships, etc., various factors play role here.!
2. Regarding subjects in demand - All have equal importance and demand in ECE. so, go with your interest.
Here the question is what is the scope for scholarship?
Depends on the university's and country's policies. Can't be said in-particular.
There are no specific exams to study abroad except those you know.(GRE & TOEFL) In fact, these are just to make you eligible to study in English medium abroad. But there are some universities take admissions after an INTERVIEW with the student. For this, you need to have subject knowledge, confidence and good conduct.
In order to get admission in foreign universities especially in USA then you have to appear for GRE and TOEFL/IELTS exams. You have to score well in these exams.
Generally admissions and scholarships are given based on first come first serve approach.
So, you have to apply to the universities prior to their official deadlines.
In order to get into top universities you should have a good GPA i.e., at least a GPA of 3.25 on a scale of 4.0.
Apart from these attributes, even your quality of application is also taken into consideration. Your Statement Of Purpose(SOP), Letters Of Recommendation(LOR) and Resume have to strong enough so that they should with stand to high competition for admission and scholarships.
If you want to pursue Masters from European countries and Australia then appear for IELTS exam.
Regarding universities, it's better to go for universities which have a good NRC Ranking.
Here is a list of some good universities based on their NRC Ranking:
Massachusetts Institute of Technology
Stanford University
University Of Illinois-Urbana Champaign
Princeton University
Georgia Institute of Technology
Cornell University
California Institute of Technology
University Of California-Ann Arbor
University Of Wisconsin
Duke University etc.
Please inquire about each university through Internet before getting admision.

The purpose of the M.Tech course is to give a specialized training in the field of engineering. Quite a few institutes intake candidates on the basis of the various entrance exams.
