Oops. My apology. I was at the retreat and I just mentioned what you would do when you understand the overall course. Yes, I'd definitely recommend getting all 3 levels. I didn't get the home study materials yet - but in your manual, you should have a chart of year & period for your home (or when you moved in). That's the base guideline unless you have done a major renovation like changing all doors & windows & painting the whole house. Be specific about taking the readings with your compass - see if you can avoid electrical equipment (at least turn off) and metals.
Did you see me in the DVD? Ha ha. I was showing my mom that "look, I have a DVD out now" - LOL.
