Where did You find the 3rd set of magazines for the art teacher? as I know from reading, the Dev moved them a few times to make it more difficult to find.
I have gone to the pool a dozen different ways and never found a way yet to go further than a BJ with Cassie, if there is a way, lets hear it people, but I dont think there is a way yet, and I dont think access to Mayor Rumps house is in this present update.
The gym teacher, I have gone there endless times, seems there is no way at present to complete that even with full stats.
This game at present is huge, and it is set to become major huge I hear, great game tho.
