Same here. My parents initially started us on the the Baltimore Catechism, but then dropped it, deferring to the lesson plans of the (liberal) CCD teachers. I learned nothing after that. Not until I discovered websites like Catholic Answers. I've learned a lot there. I ought to just go back to the Baltimore Catechism and read it.
Catholic Answers is fabulous. I listen to them on-line all the time. Doesn't hurt to review the Catechism from time to time, either. We homeschooled, so I was constantly reviewing, along with the kids.
