Sandeep, if you are a Service personnel and if yous son has been studying in Gujarat since 9th and might continue until his 12th, he is eligible for Gujarat State Quota. But for that you will have to submit Gujarat domicile certificate. But again as you are in the Army, your service certificate might be just enough and domicile certificate might not be required. But to be on a safer side, please get a domicile certificate done so that you needn't have to rush in the last minute.

Hello Sandeep

If your son clear his high school and 12th from Gujarat, he will be eligible for 85% quota,Quota depends on the basis of board exams state.

I hope it helps.
