What are good jobs for college students planning on going to medical school?


I am a college freshman and am planning on going to medical school after I graduate. I know I need to get some sort of experience in the medical field to look good on my applications. I was wondering what types of summer jobs I could get that would be good experience in the medical field. I know a lot of these jobs require some sort of training and I was hoping I could maybe do some online training so I could get a better and higher paying job. If anybody can help me out on this that would be great, thanks.
