First of all you need to understand that the college you are talking about is a private college affiliated to aktu and the condition of private colleges in india is not hidden they are just money making machines. Though jss is a decent college and it has some provision of direct admission through management quota so even you don't get admission through merit you might get it through management quota no need to worry but I would advice you to reattempt jee and get admission in a good iit/nit/iiit.
