you should meet the college requirements of ielts for ur program.....otherwise in general category there is not any condition for ielts scores....
to make this point clear....like in spp there is condition that student have minimum 5.5 each and 6 overall ielts for diploma and 6 each and 6.5 overall for bachelor's ...... the students who can't fulfill the ielts requirement under spp, they can apply under general category as there is no minimum requirement of ielts.....
This information is on the basis of my knowledge and research. .......m not sure if its 100% accurate....
you can cross check ...
