I haven't had the chance to read your first post so Welcome to this forum!
About Pioneer school...I attended it last year actually. Unlike you, I was totally mentally in at the time so I thought it to be such a privilege to receive this special encouragement and instruction that few others would have to chance to enjoy. Overall, I did like it except that I was trying my best to prepare for any question in the book, look up every single scripture (taken out of context) that I'd not get enough sleep and getting up early for the next morning session was really hard.
If you care about appearances, just jot down one scripture for a few questions instead of going overboard. This way the friends won't look at the white pages. Not really cool to miss out on the fine spiritual banquet, right?
You'll receive the schedule the first day (Monday). There are no classes on weekends, so it's a total of 10 days Mon-Fri between 9:00 am - 4:00 p.m, with a 1 hour lunch break 12:00-1:00.
You have an excuse to miss the mid-week meeting, and even the Sunday one if you're so busy studying...
During the 2 weeks, you'll get to go out in FS 3 times: once door to door, another time to follow up a RV you found from d2d (during the 1st week), and the third time to start a study (on the second week), I know...yeah right!.
Something I remember finding out during my Pio. School was that the tetragrammaton didn't appear one single time in the original copies of the Greek Scriptures. When our instructor said that, I was totally shocked. Others seemed unphased by it though.
Feel free to ask about it, the experience is still fresh in my mind. One suggestion for you is to ask questions, there are opportunities to do that at the end of each study but few take it. The instructors know pioneers wouldn't ask 'apostate questions' so they encourage you to pose questions about things.
