Hello, I hope you are doing well

With reference to your above mentioned query, I would like to tell you that you don't need to worry too much about your cancellation in KCET for your College admission.

You can easily cancel your admission in KCET allotted college if you don't wish to study further or if you don't like that college. Then if you want, you can quit engineering after 1st year.

You would have to write a mail about your issue and your complete situation to the respective college authorities.

Also, if you have paid the complete hostel and college fee then it varies from college to college that how much are they gonna refund. In some cases you don't get any refund and in some you get after some charges.

Hope this helps
