Hello

Firstly if you fulfill the eligibility criteria to pursue BEd through distance mode as well as the institute is recognized, you can definitely go ahead with it, for example if you pursue BEd from IGNOU then it's recognized as well as valid,  prior to applying for any university through distance mode, check out if you fulfill the eligibility criteria and secondly the degree provided by the university is valid or not, my personal suggestion will be if you're planning to pursue MCom and BEd simultaneously, go for BEd through regular mode and MCom through distance mode, since BEd is a professional degree, it also involves practical experiences, so doing it through face to face medium is always best, the rest is up to you, you have to decide what works for you and what doesn't.
