is it worth going to t2, t3, t4 schools if you are barely paying much for it (i.e scholarship)?
T2, yes. T3 and T4, it depends on the school, where you want to practice, the overall quality of the institution, etc. (those considerations would apply to the T2 as well, but are definitely much more of a factor for T3s and T4s). Over all, I would say that it makes a lot more sense if it's a T2; with schools lower than that, you may be seriously hampering your employability post-school (particularly with the current state of the legal market).
