can I do double MA in the same subject but one regular and another in distance mode ?
There is no restriction in such a scenario, you are free to do dual masters (2 masters in the same subject). But it will serve you no good. People do 2 masters in the same field because they want to gain the experience or knowledge that may be introduced to the field as a new prospect after completing their master's. Doing dual masters at the same time will serve you no good, trust me. Instead, you can do 2 masters in two different subjects, one in regular mode and the other in distance mode
