Hello!
I’m a student with an interest in Classics and Philosophy primarily, with tangential interests in History, Anthropology, and the like (Humanities, go figure). I’m also looking to going into law school after undergrad (mostly because of a concern about snagging a teaching career in Classics in higher ed and making enough money to eat, etc). This is not to imply I don’t have a genuine interest in law, as it would be hard not to have a mote of interest in it if you’re interested in the Classics, but it is to say that I might prefer a career in academia if circumstances allow.
Does anyone here have any experience with any of these schools and student’s acceptance into law schools (prestige included)? My main concern is Reed & Bryn Mawr with their Honor Codes. At Reed, you’re not provided your grades unless you ask or are failing, and at Bryn Mawr, I’ve only really found that you can see your grades after the semester ends. Not being able to monitor your grades seems like a precipitous line to walk if a GPA is so important to law schools. The solution to this is obviously to work as hard as possible at all your courses all the time, which is certainly what I intend to do- it’s just that I can foresee regretting not giving it that extra push or meeting with a professor more often after getting my grades back at the end of the semester.
Advice appreciated!! Thank you! 
Here is the list of law schools that Reed grads most frequently attend: https://www.reed.edu/ir/success.html The list includes many of the leading institutions
BMC may have a list of their own. E-mail the school and ask them but I didn’t see it on their website. Bottom line: graduates of both schools are accepted into top law schools
BMC alum here – I’ve never heard anything about BMC not having access to their own grades before the end of the semester, that certainly was not the case when I was a student. BMC does have a strong culture of not being competitive with others about grades, or about grade-grubbing – the culture is about doing your own personal best. The Honor Code, like at Haverford, creates a culture of mutual respect and accountability, but I’ve never heard anything about Honor Code and students not being able to access their own grades during the semester.
If you have a source for that, I would call Admissions or the Dean of Students office to ask about it.
Reed definitely takes an unconventional attitude towards grades (also other things, like sports or the USNews rankings). It’s true that you won’t know your grades unless you ask (or are failing).
But to my knowledge, Bryn Mawr and Haverford follow the conventional model. You take tests, you write papers, you get grades on them. A final grade for the course is posted after the end of the term (after final exams are over and all papers have been turned in). Same as other schools.
