I appreciate your keen observations in Ask Experts section. There are some questions on which you might find varying explanations but they are not contradictory in their nature. There are some finer points in some questions and there is definitely some scope for variations in answer.
For example, UGC allows only for one regular course and one correspondence course at a time but if someone brings details that one is doing a regular course in the morning session and another in evening session then UGC may again consider it as correct. In fact, UGC is already contemplating for allowing this - two regular courses simultaneously - and that might get the approval of the Govt also.
We have a plethora of rules, regulations, and guidelines in each of our educational activities and while explaining a particular aspect there could be a difference of opinion and it may become a matter of discussions among the people knowing that thing in details and sometimes it is also possible that a few among them would correct themselves after knowing the exact stipulation. So to that extent, these variations are admissible. We all are in a learning process and no one has all the knowledge of the world with him. We only try to do our best by giving the most reasonable answer.
Hope it gives solace to your query.
Knowledge is power.
