A degree is a degree and has the value of a degree if it is from a recognized university. I do not know about the ranking of the open University examinations. However, if the Dr BR AMBEDKAR OPEN UNIVERSITY HYDERABAD is a recognised all India level university course. Therefore, if you are sure that the open university from where you obtained the degree is a recognised one you can apply for the jobs. You need not have any doubt if the job applied is for candidates with BA degree qualification.
