B.A

First of all, I would say that don't go for B.Ed. In distance mode because every school values the regular B.Ed. More than the distance mode as it is of totally practicing a profession. Besides this some universities are there if you do B.Ed. From those then it will not be considered by the schools as those are not recognized by NCTE (National Council for Teacher Education). Therefore, I will suggest you to go for regular B.Ed. So that you can be an effective teacher.
