I too went to a Jesuit college. I agree with your assessment. Some of the most difficult classes I ever attended. Slouch just even a teeny bit, you paid.
The non Jesuit instructors were lefties. The Jesuits were not. And they did treat us veterans well at a time when we were getting dumped on by everybody.
Unlike many Catholic my age, I can't say that Jesuit training is the best. We had some scary years with our daughters when we thought they were lost to the Faith forever. However, what I can say proudly is that all my Jesuit trained children are practing Catholics today.
