Dear John:  

I'll be glad to pray for you. You seem like most young men who are called to the priesthood: normal. You are probably in good health, have intelligence enough to at least handle college courses, etc. Nevertheless, when you apply to the seminary you are going to be asked for doctors' certificates of good health, transcripts, etc, to verify all the above. The psychological testing is in the same vein - just to make sure of what is most probably already evident to anyone who knows you, that you are normal for your age in character, emotional maturity, personal identity, etc. Forget about the couch and the swinging watch on a chain, with merciless probings into the depths of your unconscious... what you usually do are some standardized written 'inventories', and an interview with a psychologist based on the results of the written material. Psychologists who serve seminaries usually believe in grace and place a high value on morality - so if you have been living your faith you will not be dismissed as hopelessly neurotic. Hope that helps, and I really did mean I'll pray for you.
