Dear candidate.... hope you're doing good..

Well, basing upon your rank in Comedk, it seems like you may not get admission into some reputed government college in Karnataka but still you can give it a try at the time of counseling and it's better to apply for colleges in your own home state so that the chances of getting admission are high. But you may also apply for other deemed universities and private colleges offering b.arch course.

Hope this helps you out.... 

All the best!!
