You can try for management seat but Management quota admission and fee cost is not advertised openly by any of the colleges/universities across India as being a paid seat it totally depends on the discretion of the college authorities
Get in touch with the desired college for detailed information.

If you don't have any category advantage, I would say you drop one year and study hard with a focused approach. Take JEE, BITS and other exams again next year make a good career with a good college.

I want to suggest you that please aim for 250 as it is a secure score, you will definitely get admission in the colleges such as DTU, NSIT or NITs otherwise there might be chances that at the end you will not get your desired college. All the very best from my side.

It depends on you as if you are satisfied with the college and branch, then you can freeze the option and pay rupees 5000.

You are not eligible for admission into any college through JOSAA counselling.
There is no chance of getting any thing at verification also.

NIT-Trichy, NIT-Warangal, NIT-Calicut, MNIT-Allahabad, NIT-Durgapur.

No, I don't think so. Go for cutoffs in previous years, you will get a very fair idea.
