Don't do it if your just trying to jump through hoops to have something "cool" to put on your application. Its alot of work, and listing it alone isn't even to seriosly impress any schools.
Look into being a health and saftey instructor! Better schedual...
The red cross is awsome, almost all of my volunteering was through them, and i really feel like i got something out of it.
Don't be one of thoes stuipid pre-meds who screws the red cross over by helping just enough to say u helped so u can list it on your app.
