In college, I watched my roommate go through SCCA licensures, and he eventually ended up with his National License. He started off in Formula Fords and ended up in a B Sports Racer which is a very fast class.
My roomie quit racing for many years, and later opened a Miata race car shop in Florida with dyno's and the whole works. He campaigned two very competitive Miatas for many years.
My Facebook is full of people I went to high school and college with. His Facebook has famous race car drivers, including many that race or have raced Indycar.
If you want to go to a racing school, go to one that issues credentials so you can race a specific class of car. In other words, don't go to the Richard Petty Driving Experience if you want to drive a rally car in Europe.
