Hello,

As per recent guidelines, candidates can now pursue two programs simultaneously but the only condition is one has to be done through regular mode and another through distance mode, hence you can pursue your teacher's training course through regular mode and graduation through distance mode, distance learning courses are more about self-efforts and self-study, even though there are classes held and everything(this might have halted because of pandemic though), but at the end of the day it's lot about how much efforts you're putting in your studies, other than DU SOL you can also consider IGNOU which is one of the largest university to offer  distance learning programs, its study materials are written in lucid and simple style, similarly there are many other also to consider if you may wish to.
