Roman catholic Seminary?

List-in i heard allot of testimonies from people who entered seminary's some say they did not know anything about God or the spiritual life until they answered there calling, as we all know callings can come in many different ways, the way God wants it to be, i want to join the seminary, i know God is calling me for it, i cant say how he called me but lets just say hes givin me so many signs theres no doubt hes not calling me,but anyways, i was wondering, there is plenty of hw in the seminary heres the thing i was never great in school in the first place, what ive learned is that seminary is a spiritual school, not a from body or a in spanish they say no es una escuela de carne, anyways i do not know allot about the bible, do they teach it to us there? do i also have to have college credits or units to transfer to seminary or to even enter 1? i only have 6 units from a technical school,but i can transfer to a college and get my other 6 quickly, and so i dont know i want to hear more about the school not just basic details, describe it to me if you can no 1 has ever described it to me.
