I would never recommend production/textile at VJTI for a branch change to CSE afterwards because you must understand that most of the people in your class would be looking for the same and remember that these people are mostly of your level or above making the competition tough. You need to score almost 9.8 and above for CSE and that too depends on the availability. So basically if you didn't do well in your first year then you may be stuck up in the same branch for the next four years or maybe for the career too.
I would rather suggest you to take CSE in other clg like SP, DJ, KJ etc.
Also do wait for the spot rounds.
