Dear aspirant,

As you are domicile of Odisha, and have a valid JEE Mains score. You can allot in direct counselling session of OJEE.

As OJEE is a seperate exam you can appear for that only for experience, but according to me it will not required if you have a good JEE Main marks.

On the day of counselling you should take these documents along with you,

--> Admit card and Marksheet of JEE Mains

--> Marksheets and Certificates of 12th and 10th, and admit card also.

--> Domicile Certificate

--> Any government issued ID which includes your name and birth date with your photo

--> Some passport sized recent photos.

Best of luck..
