@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.
@DeeJayGee I have all the Cambridge Packets for the question types and PDFs for 36-76. I use the snip it tool on Windows and cut and paste them to Word. Do that for 25 questions and you have a full section.
