Dear Mugdha
Isn't it possible to send the average of marks to the universities you want to register!? if it's impossible try to improve of your other works that you've done to now,Bold them and try to show them much more important than marks.
And be careful don't ruin the rest of life because of 2 years ! of course is sad to see the bad effects of it but it wasn't a bad experience and at least you yourself now about your level!

wish you luck.

Why are you too negative, come on i've worked for a company and i didn't know anything about the position that i will take! just by confidence i could be the manager of a part of it! without telling myself if i can do it or not i just tried!
if he didn't tell you anything it means he didn't see problem during your work
trust your self!
