As per above, there will be less stress in attending Harvard Law, as almost everyone will get a reasonably decent job upon graduation. She will have a lot of doors open to her that are not open to BC and BU alumni, such as clerkships, high-level government jobs, and academia.
Some kids do fine when they go to BC or BU; many others don’t. The Boston legal market is VERY small and VERY overcrowded - in fact, it’s one of the most overcrowded in the nation, based on the number of people passing the bar versus the number of openings for new lawyers.
What a lot of us are trying to say is that the short-term considerations of not wanting to re-take the LSAT, not wanting to wait another year, etc., pale in comparison to the potential benefits of having a shot at going to one of the best law schools in the nation and the best law school in her desired geographic area. Her options are also a lot more, well, option-y right now than they will be if she ends up at BC or BU and, three years from now, doesn’t have permanent employment lined up.
