I strongly encourage members to provide an explanation with their answers and it does not have to be anything lengthy. I understand that often times one could be at work and not have the time to do so but consistently posting one liner messages such as:
"It is A, B or E"
"What is the OA"
"Between A and B, I pick B"
will diminish everyone's learning experience. One can only imagine coming to a discussion forum and only seeing the above mentioned posts and wonder what is the real value-added to be obtained in participating in such a forum. Please participate in an active way and if you believe that an answer is right or wrong, try to explain
why you think so. It is crucial to remember that there is no value in getting an answer right or wrong or even knowing what the answer is. Instead, you should know
why the answer is right; it is the
only way to a disciplined approach to obtain a good score. Moreover, it is also another way of contributing back to GMATclub and share with others what you have learned here.
