I am preparing to become a certified respiratory therapist and a friend recommended I look into Kettering respiratory therapy seminars to help me get fully prepared. They have them all of the time in this area and they offer practice test options that I would love to take. The on line information shows that these seminars really cover all of the pertinent information and that is exactly what I am looking for. I need to pass this certification exam and I do not want a bunch of unnecessary information floating around in my head before I go to take this test.
