One of the biggest regrets I have is that I slept through Latin I and II back in the 70s.
It may not have done you any good to stay awake. I took 4 years of AP Latin at a Jesuit high school, and at the end of it I couldn't say the Ave Maria or Pater Noster. Not one word of ecclesiatical Latin was ever taught to us. Now my 5-year old can say all the basic prayers in Latin, which is a lot more than I knew when I was acing the Latin SATII.
