so i am planning to join msrit in one of iem/civil/chemical/aerospace, so I am planning to work hard in first year and try to change my branch from 2nd year on (to ECE). Now what i need to know from you guys is how hard is a branch change, like if i maintain around 9 cgpa or more is it enough? and more insights would be helpful, thanks in advance.
