Hi,
If you are planning a fitness training programme, join a good affiliated institute that is well recognised and get a certification. Go for a job oriented certification. Before you pay for any such courses, ask about how you can build your career after completion which means placement assistance must be good. Initially you can work with and under the same organisation through which you did the certification. Later on, you can market yourself as a freelancer. Examples are Naukri and Justdial. As a freelancer it gives you ample chances to have personal clients and also reach out to agencies for assignment based work.

Yes, you will get a certificate after the completion of your B.Des.

You can directly visit your university with your documents, like mark sheet of your graduation. They will provide you degree within 80 days.

At the time of documents verification, there is no need of migration certificate so you could carry forward without having it. But when your regular classes are going to start, you need to produce it in the college.
