HI I am quite worry about distance learning because I have completed my M.COM 56% in Management in the year 2013 and want to pursue MBA in Australia so Will they accept my educational qualification .

I don't think this an issue with distance learning, but with your academic performance. Obviously better schools ask for better grades and higher GMAT scores. The worst schools will take the people with the lowest grades. Perhaps you will be able to compensate for your MCom results by getting a strong GMAT score?
