Hello student

hope you are doing well and safe. With reference to your query,  I would glad inform you that kcet is conducted by authorities once in a year ,if you want to re-attempt kcet you have to wait for a year . I would suggest instead of waiting for a year take admission in  any college and spend your one year to ehance your coding skills which will benefit you a lot

Hope you found this answer informative. Best wishes for your future
