M.Tech Mechatronics or Master of Technology Mechatronics is a postgraduate engineering degree course of 2 years. The subjects taught include topics such as Industrial Management, Mechatronic Systems and its applications, Wireless Communications, Control systems, Signal processing etc. The minimum eligibility criteria for M.Tech. Mechatronics in most universities is that the applicant should have passed B.Sc. /B.E. /B.Tech in relevant subjects with 60% or equivalent CGPA. The eligibility criteria for M.Tech Mechatronics Engineering aspirants is not complicated and is as follows. It must be noted that the eligibility criteria will differ from institute to institute. B.Sc. /B.E. /B.Tech. In relevant subject with 60% or equivalent CGPA
Some of the very renowned universities and colleges conduct an entrance examination for admission. 5% -10% relief for the reserved category like SC/ST/OBC students.
So, he can try for that

1- If you do not wish to study more or do not have the necessary resources, then you can get technical jobs by doing an ITI course; otherwise, if you want to go ahead in the technical field, it would be better to do polytechnics at less expense and less time.
2- ITI courses have a duration of 2 years, whereas Polytechnic courses have a duration of 3 years.
3- Benefits of ITI courses: easy employment, short course duration, early job opportunities, cheaper than other courses, and government-approved course, could be perused even after the 8th, 10th, or 12th. Benefits of Polytechnic courses: They offer more training, practice, and practical knowledge than other courses. Polytechnic courses are more similar to engineering courses; therefore, entry into the engineering field is easy. Some companies prefer Polytechnic students more than engineering students. Polytechnic students could peruse an engineering course and join an engineering course as a lateral entry.
4-year.
4- ITI courses are comparatively cheaper than the Polytechnic course stream. While the fee range for ITI courses could be around INR 1,000 to INR 10,000, the course fee for Polytechnic courses could be around INR 10,000 to INR 20,000.
5- Jobs: ITI students work as tradesmen mates, mechanics/co-Operator Electronics Communication System Apprentices, electronic communication system apprentices, housekeepers/apprentices, and so on, whereas Polytechnic students work as junior engineers, IT assistants, PSU jobs, clerks, technicians, and so on.
