@Charles11 to answer your question what I'm starting to do with these uncommon questions is make a list in an excel sheet and save it for a later time. I also try to memorize the pattern used on that question type.
Usually you add your PT answers to the 7Sage sheet after you've BR. Some people like to add their answers first to see their score and then BR. It depends on what you think works best for you.
Sorry about the uber lack of response. Been out all week (as in sick, not fun because who has fun besides studying while studying for the LSAT). Will be there PT52, Monday 8PM
