hello aspirant,

I hope that you are doing absolutely great.

With reference to your above mentioned query, I would like to tell you that YES, you can change your Engineering college from 1st Semester and can write your CET exam again. But, I think that you need to give the whole 1 year fees and it will not be refunded.

It also depends upon other colleges, whether you need to give some other entrance exams as well. You need to talk to your College head and the University to leave your college and the reason for it. Then you cna join other engineering college through KCET Exam.

I hope that this will help.
