GATE

You shouldn't change your line as you are an engineer then you should prefer M.Tech and many colleges have their own criteria for admission process. I would suggest Indo Global Group of Colleges to prefer as this college is in Chandigarh and has good infrastructure as well as placement assistance.

Anna University is the main conducting authority which organizes a state level entrance exam called as Tamil Nadu Engineering Admissions (TNEA). The application form will be available from the first week of May 2017. Some other university level entrance tests are SRMJEEE, AEEE, VITEEE, etc. Students can also apply for JEE Main for admission into engineering courses in Tamil Nadu. So, if you want to do engineering in Tamil Nadu start preparing for this entrance exams.

MCA graduates are eligible to appear for GATE to take admission in MTech at IITs and also to seek a job in Public Sector Units. M.Tech CS or M.Tech IT from IITs and NITs has a lot of market value with very good job prospects.

You are advised to do a short-term course on computer hardware maintenance and repair so that you have good hands on exposure on PCB repairs. This knowledge will be helpful in circuit design and its practicals.
