Excuse me, but why the hell would you want to post your shortcomings? You are vying for a spot amongst many, many, many, qualified candidates. If at all you get an interview, you should only talk about these there, in person. Mistakes on paper are simply flaws or better stated, "chances to hurt your application". You may have made mistakes, but point these out through what you hopefulyl did to correct them...improved grades, ect...and hope to god you get an interview. Good luck.
