hello

First of all, if you don't get through the entrance then there are various good private universities like Sushant school of art and architecture, Amity University etc. that offer architecture, maybe you'll find them a bit more expensive but if you're genuinely interested you can make a career in it and make it worth.

Other than that you can go for interior designing, there are many other similar professions like industrial designers, construction managers, town planners, etc. Assuming you're from science field, you can apply for B Tech civil engineering, it is some what related to architecture.

All the best!
