Yes, you may change your Engineering college after completion of the first year. Then there you may get chances that you may change your Insitute and get a new one but they might have some conditions like First you clear all subject, Second only that that institute who have some sit left or empty then you may join them. Some other that information you may get in your College offices.

Good luck.

Hii aspirant ,

Coming to your question I would like to tell you that yes you can change your engineering college after the completion of the first year but only if you have another option with you like if you give jee mains and got selected in any nit then you can leave same condition goes for the other engineering colleges , but it is only in the first year ,and you must have the alternate option with you ,

Hope this helps you , good luck.
