If you can get the BP Weekly, there is a list every week of all the shiurim. You should check first though, because they are not always updated. The BP weekly comes to every home in Lakewood for free, so if you are living in Lakewood, you should be able to get it. In the worst case, you can go down to the BP office to get a copy (I think it’s on Fourth Street between Clifton & Madison).
My impression is that you are post-seminary girl. If that is correct, Rabbi Grama gives a weekly shiur that girls love. Also, there is an organization called Pninim or Pnima (there are 2 organizations with similar names, so I mix them up. One is specifically about tznius -that is not the one I am talking about). They have weekly shiurim by different speakers. Originally, it was meant to be only for single girls, but I don’t think that is the case anymore, although they may sometimes have some shiurim specifically for single girls.
Rebbetzin Dina Fink had tried starting something for post-sem girls at some point. I am not sure if it ever took off or not. It had a name that begin with a Lamed – something like Lech Lecha.
All these things should be in the BP Weekly.
