Distance

You can do it. But, that is not legal. Doing two degrees simultaneously is illegal. You will have to drop either of the courses. So, you better concentrate on one degree instead of planning to do two degree at once.
Also, MITSOB is extremely strict about their attendance criterion. As well, recently, MITSOB is introduced with the trimester system with which one is much occupied with their college work itself.

Hello Shashank,Supreme Court of India has ruled that courses which require lot of practicals can not be offered by any institution in distance learning mode. Not only this, it cancelled degrees given out fir many years.

The application form is available at it's central office you can get it from there the charge is about Rs 25 or by sending bank draft of Rs 50 in favor of it, shortlisting is done on the basis of merit.
