This is just me speaking for myself and is not official info about Greek life at Northwestern, but here are my thoughts --
For time commitments, it varies from chapter to chapter. All chapters have weekly meetings which are required. These are usually on Monday nights and typically last an hour or two. If you decide to pledge, you will also probably have to attend mandatory new member meetings for your chapter. You will probably have other occasional mandatory meetings for things like recruitment, too.
Social events are optional. Philanthropy/service events are likely not.
Everyone at NU is focused on academics, so you would not be alone in being focused on your grades if you joined a sorority.
