I asked them a few pointed questions (e.g., what kind of credentials does your instructor in my city have, how did s/he do on his/her LSAT, etc.) and all I got in reply was a request to take a diagnostic and then they would discuss that kind of information with me after the diagnostic.
It seemed like a strange reply to me. I mean, if their instructor here in my city has credentials that are worth publicizing, you would think that they would tell me something about him/her in a bid to interest me in their program. It just seems like an odd way of dealing with/attracting a potential customer.
