ADMISSION IN VIT IS DONE THROUGH THEIR ENTRANCE EXAMS THAT TOO YOU'LL HAVE TO Wait for the ranks. Nothing is sure. It totally depends on branch. Many students will be ahead of you who got 90+ in Jee Main as well in. PCM marks in Boards. If you want high demanding branches like CS/IT chances would be less in Vellore or Chennai campus. But however you may get in higher categories if luck favours. Similarly ECE and EEE. Other branches like Mechanical, Civil, Biotechnology you will easily get in main campus. It's better to wait for the rankings to be published by the Institute.
