You required 80% to get admission in top colleges of Pune and Mumbai for BMS course.

Hi,
No, you cannot get admission in the above course without MAH-B.Ed
Admission is through CAP counselling based on the score obtained in Maharashtra B.Ed. Entrance Examination (MAH-B.Ed).

See, in some of the government colleges, it may be possible but in the private colleges, there is nothing like that.

Yes, you can get admission in Karnataka or another state through lateral entry.

I have very little knowledge about Ferguson College, though I can say that statistics as a subject is very little understood by us. But it has a humongous growth in the future to come. And coming back to MA in Economics from JMI, it is one of the awesome courses of JMI, the faculty members are well trained and they do have a certain infrastructure and more to study economics anywhere in the world or given any time of the history has tremendous opportunity in terms of learning how economies work in the world.

Yes, there are many colleges that consider JEE marks and class 12th marks for B.Tech admission. You should try to get your best in JEE. All the best.

There is never any restriction on open or distance study. Just issue comes when your exams dates coincide. Else, all depends on your time management skills. My best wishes for your future. :
