M. Tech can be done only after your bachelor of technology degree and MSC can be done after Completion of BSC

Hi

Mtech course is for 2 years while MS is for 3 years.
In Mtech you will be working as teaching assistant to your professor while in MS you will be working as research assistant.
Your work depends on your professor.

Most IITs allow both Mtech and MS students to sit for placements together.

Thankyou

The diffrence between M.TECH ans M.S is the study orientation and pattern.

M.TECH is more detailer cource with a lot of study.

on the other hand M.S cource is basically more about practical knowledge and self study about the subject and project.

Mtech is btech with research work . In other words , you study majority subjects of btech in mtech , the subjects are more broader than btech . And secondly you have to do research work on your area of interest .
Ms is pure research oriented and has very less subjects to study like in mtech. It is like a mini Phd . You have to mainly focus on your thesis work .
Mtech is more common in india
Ms is more common in usa and other countries
