This chart is interesting.
One wonders why biology students do so poorly while classics and religion students do so well. One hypothesis: classics and religion students learn critical thinking skills while biology students are taught to parrot the central dogma. The chart is from a study of which undergraduate majors correlated most highly with success on the LSAT. See here.
I note that my own undergraduate major (accounting) also faired poorly. It seems my LSAT score (97th percentile) was an exception if this chart is any indication.
