Real Estate Agent!!!?

I am considering a future job in real estate. Im still young and have the opportunity to go to school and this field definetly interests me. The only thing is I dont know is where to start and where I should look into going to school at. Should I go to a company and get my feet wet or should I go to school first. I understand that this is a comm based job but are their other job opportunites that do require pay w/o being a real estate agent first. Just to see if this is right for me it would be great if I could get some info on this matter. Also if anyone can give me some ideas on schools in san diego and even recommend any companies I would greatly appreciate it, thanks!
