CAP PI was a disaster

I scored only 84 , but it was my second attempt. Got cap calls because i was obc. But the interview was a disaster. They asked alot of academic questions which i didn’t even heard of. I had to i Don’t know for everything 😭. But i also heard other panels asking more gk and current affairs. I was well prepared with my academics, but my mistake was i only focused on core subjects. But that guy asked from small ones which i am sure no one will be remember even they studied those subjects. I don't know what to now. I haven’t applied to colleges like wellinkar due to financial problems. What will i do now 😭. Please don't say get a job and repeat. I hate this exam.

Edit : NIT trichy is open now. Should i apply it as a last resort ???
