Chances of acceptance during R3

I gave my GMAT FE last week and got 685(97 percentile). I have a decade of Work experience in the Indian Revenue Service and as you can guess my age(34) really isn’t going to help my chances as I want to pursue a regular MBA in any of the M7. Just wanted to get an opinion if there is any point in applying during R3 now. How bleak are the chances compared to applying in the previous rounds.

I ask because applying even for three universities will cost me a month of my pay. Realistically speaking if the chances are negligible, I will apply for next year.
