ok seriously? you have asked this several times. there is no magic number that is going to get you in. at my school at least .. after you get past the preliminary cutoffs (above a certain gpa, above a certain oat score) then its all about how you interview and how you can explain why you want to be here. if you feel you have had enough experience to know why you want to do this for the rest of your life why does it matter? no one is going to say.. oh wow that guy was a great candidate.. but why did he only have 30 hours of shadowing vs. 34... there is no magical number of hours that will get you in anywhere. check to see if the schools you want have a specific number, and as long as you are above that just stop worrying about it
