I'm just finishing up with my Pre-Baptism lessions with the missionaries, so it's all fresh in my mind.
I met at another member's house because my home was not available. The Elders study at their home until 10am, so our lessons began after that. They were open to meeting at the meetinghouse, too.
Our first meeting was a little like any new meeting -- get to know you chit-chat, trying to remember names. It was just what I needed, though. We watched the Restoration video, and I could ask a bunch of questions. You'll get "assignments" to read parts of the Book of Mormon, but it isn't overwhelming at all. They will give you brochures during each visit on different topics like The Gospel of Jesus Christ, Tithing, and the Word of Wisdom.
I'm getting baptised on Sunday. Best. Move. Ever.
While you're waiting for the missionaries to schedule your meeting, you can go on Mormon.org and chat with the MTC missionaries in Utah. They are so helpful and can answer almost all your questions.
Also, there's an app with the Teach My Gospel workbook that the missionaries use, but I would suggest waiting before you get it. Trust that Heavenly Father will reveal the information you need in the time you need it. If you get the app and start poking around at lessons intended for down-the-road, you might get confused or discouraged. Be patient - we're all on eternal time now, right?
