M.S

Hi
M.Tech in India is course based. U give exams in ur first year of M.Tech and need to earn the required credits. In ur 2nd year,u have to undertake a project & when u finally present it at the end of ur 4th semester,u are awarded ur M.Tech degree. Duration-2 years.
MS/ M.engg abroad is thesis/research based. In ur 1st year,u'll have to decide which discipline u'll be researching on & u'll be allotted a guide. Once an MS student(designated as a research scholar) is done with his/her 1st year,he/she will have no more classes.The research scholar then actively pursues his/her thesis and is expected to come out with a research paper.
Duration-1.5 to 3 years
