Please write the course name for which information is sought. However if I talk about B.Arch course, the 50% of seats will be filled through ACPC conducted by government of Gujarat for the students who completed 12th from Gujarat. Remaining 50% seats from all India merit. Hence you will fall under the all India merit for 50% of seats. So there is no reservation for Gujarat state domicile.
