Since we have a nice audience of women in science here, I'm going to recommend to all of you...study groups! (And the same to the men here who want to meet more women...just keep it focused on studying, and let nature take its course AFTER the regularly scheduled study session.) Women do well in cooperative learning settings, so study groups can be more effective for women than studying alone. You do still need to study alone, of course, and show up prepared for the group meetings, but that added group discussion can really solidify your knowledge and recall.
