A z-score of zero means Mary scored exactly at the mean on the GRE, and a percentile rank of 50 on the LSAT means she scored exactly in the middle, better than 50% of test-takers. Both positions are equivalent in terms of standing relative to other test-takers, indicating she did equally well on both exams.
