First of all you should try for B.Tech if not possible then BCA where you should majorly focus on competitive coding or development so that you can easily get a job of 30-50k and then you should think of specialisations like machine learning AI data Science which can give a big boost or you can go for MBA if you have interest in that side.

Yes you can take admission in BCA on the basis of your board result or the test which some colleges put across.
