Does anyone know the process in as far as medical certificates with regardes to Class 1, 2 and 3.  I want to get one but dont know what is all inlvovled with what they do as far as classifications.  Do they check you more thoroughly for a Class 1 as opposed to Class 3?  What do they check for?  Do they check for anything and everything possible?

I am in a career change at 37 y.o. and interested in learning how to fly.  I would hope that someday I could learn how to fly a jet.  I was reading that it would be very wise for a person to go to their family doctor and get a physical and then goto a FAA medical doctor.  If you get denied with the FAA doctor then you have to goto to one at Oklahoma City, OK to get things worked out.  If I goto my family doctor for the intention of getting a Class 1, then what do I tell him to look for or test for?
