@momof2eagles Pomona has grade inflation with an average above 3.5, according to:

Among the top LACs, Swarthmore is one of the few with a reputation for grade deflation and course rigor (similar to UChicago among top universities).
Those 4 are all great choices, but IMO they are different enough that each should stand out among the group in different ways: WashU as the only research university, Pomona/Bowdoin for West and East Coast environments and reputations, and Swarthmore with the aforementioned focus on course rigor,
