I have a (now distant) friend who spent one year in a science gradduate program, quit because she couldn't handle it, and went to law school.

She made the statement that a JD is equivalent to a Ph.D. - I kept silent but strongly disagreed. I've since seen a Ph.D. program for lawyers which required advanced training beyond the JD, and other lawyers I know disagree with her statement, so I am pretty certain she was wrong (I suspect she needs to be able to believe she has a degree on the same level as a Ph.D.).
