Don't worry. It wasn't all bad back then, They taught us about the role of conscience, the conditions of sin (meaning that you don't necessarily sin just by committing an action or omission) and the mission of the Church to carry the good news (not, apparently, to police every individual's actions while getting myself into heaven). . A lot of the stuff you hear from us oldies is a perversion of what we learned in grade 3. I can assert this because I'm an orthodox Catholic. Tridentinus has said so.
