Help! I made a mistake on my college application!!!

<p>UGHHHH I CAN'T BELIEVE I MADE SUCH A STUPID MISTAKE. I seriously don't even know whether its worth correcting, but on common app, for one of my activities (Cultural Club) I put 8hrs/wk 8 wks/yr, when it was really 1 hr/wk 40 wks/year. I think this happened because I didn't realize we were supposed to rank it according to importance, so I switched that club and track and repeated the same approximate time spent twice. I mean its not really a big mistake, but it will probably make me look really stupid and undermine all the work I did in that cultural club. What should I do? I'm so ****ed off that I did this right now. I for real quadruple checked my app.</p>
