I had 22 back logs in my engg (2006-2010) but in the end of final year after 4.2 our university held supply's of both the sems. I completed most of them but I sub I completed in 2011 (our university conducts supply exam too late they conduct 2 and year 1st sem supply 1moth before 2nd year 2nd sem )

Now I'm thinking to write my gmat if they ask about my back logs what should I say??

Tell the TRUTH.
