710, very well done!
I too am considering Rottman and Schulich, B average in a 4 year business program. Yet to write the GMAT though I picked up my first book (Princeton 2012) today, I wish you the best! unfortunately I don't know enough to answer your question but 710 on a GMAT will certainly make a 3 year degree almost irrelevant. Great job, keep us posted on what happens!
