B.Tech

1. Distance Master's degree programs in engineering and technology is not accepted by the leading recruiters and employers. Hence pursue the regular Masters programs.
2. A Master of Science M.Sc Degree is typically awarded in disciplines classified as the sciences such as Mathematics, Biology, Chemistry, Physics, Statistics etc. While MS is a professional degree. Studying MS mainly prepares students for either entering high-level careers or to enter doctorate programs at an institution. MS degrees are completely course based, research-based or usually the mixture of two. Anyone who has completed the Bachelors' in Engineering or Masters' programme in Science and Humanities can do the MS programme.
3. The major differences between online learning and distance learning is geography. The big differences include Location, Interaction and Intention. Distance learning means no in-person interaction at all. Online learning works as a supplement to direct teacher guidance.

Hello Rishabh, It is nice to hear from you that you want to do B.Tech now. However you have not mentioned what you are doing presently and from which state you come from. However generally speaking a student has to first clear his 12th with good marks that is above 75% to get admission in reputed institutions. The state to which you belong will be conducting an entrance exam or would have assigned some entrance exam for admission to engineering colleges in your state. At the national level you have to appear for JEE Mains for admission in NIT and appear for JEE Advanced for admission in IIT. Over and above these if you want to seek admission in any of the Deemed to be university then you'll have appeared for the entrance exam conducted by that particular University. Best wishes to you.
