M.Tech

Hello Sampath,
Admission in VIT University is based on your rank in VITEEE exam. So if you have appeared and got a good rank then you can get admission in any of the four campuses of VIT. Only with your board percentage, you cannot get admission.

You need to first decide your career aspirations & then based on it take a call. Since you are a B.Tech in ECE graduate. In case you are keen in the said area then you could pursue professional certification in specific technical areas that are related to your field. You could also pick up a work assignment and then pursue a course that helps you acquire advance skills in your work area.

Yeah you have to appear in either IELTS or Gre without these examination you won't be able to get student visa in any other country
