I had the 3 lr, 26 26 25, rc 27, and lg 23. Based on this one of my experimental was a 26, because if not that would be 102 questions. Luckily the two 26s were my worst sections.
@singerhanna I'm not sure about the number of questions...i never checked how many there were but the fact that I think I had 25 is making me freak out and think I misbubbled haha
I wouldn't buy an LSAT-specific watch. I got a cheap analog Casio. $10. Takes less than a second to reset to X:25 between sections. When the big hand is vertical, time's up. I can also time the break! I reset to X:45.
I use the "note" feature to record my original score for retake. For instance, in the note I'll write "6/25 168" so that i know what my original take score was.
