But of course you can weigh in! Groton Day is a caricature of prep school life, not an every day experience. I am basing my experience on our visits. Take a look at Groton's website - the kids are dressed pretty normal, much as they are at your LPS.
Back is December you were complaining about the strict writing structure her BS required - do you know anything about legal writing? They don't encourage or reward prose. Law school isn't exactly a fall back position - it's 3 years (full time, longer if you go part time) of school after college, and then you have to study for and pass the bar exam of the state you intend to practice in, then await the admission process if you pass. It's a 3.5 year minimum process to get your license. Skill on the SAT, SSAT, GMAT, MCAT or any other standardized test is NOT indicative of success on the LSAT, it is testing for entirely different things. A word of warning - almost no one goes to law school for free. They give you basically unlimited loans that have to be paid back.
I ended up buying from a mix of school book store, amazon, and other private sellers on line, wherever I could find the best price. Just searched amazon by isbn number and no issues getting the correct copy. Bought new where an online code or cd was part of sale to make sure I had no issues. All the rentals I saw were for a single semester, so I avoided those. The only problem was one book was water damaged in transit. Mail man must have dropped the package in a puddle. A quick email through amazon to the seller and they immediately shipped me a new one no questions asked - they didn't even want me to mail the damaged copy back.
