You can contact college authorities regarding it. Nowadays college don't take original certificates. If they are not giving certificates, better to apply for duplicate ones from school. Not to go for legal action as it may take long time and other resources as time. Better to talk and find some way with college authorities.

Don't select engineering branch according to recession or due to any external influence. It is very hard to guess it. Always select branch according to your strength and syllabus content. Every branch has its own importance and need in society. I can prefer you some branch like Electronics, computer, Artificial intelligence, robotics which has bright future. Rest your choice and don't blindly accept expert answer. Do some exploration from your side also.

Hi,
Admission Process
Register and Apply
Interested candidates can apply online with the required information. Entrance Test
Eligible candidates need to appear for the entrance test conducted by the Maharaja Sayajirao University of Baroda. Final Selection
Admission is based on the marks obtained in the entrance test.

There are many medical test which is conducted. But there is no mention of physical tests like running. Exercise is mentioned but I think it is pushup may be. For ground work, I think physical fitness is required.

You may pursue Ph.D in economics after MBA; I don't have any idea about CSE as it is a technical branch and for that, you should have done your B.Tech in CSE.

You might get CSE, but I think you will get admission in 1st year. I don't know about BCA. But before applying to any college, first contact the college and get full information about it.
