Re: sims 4 university Guest Lectures

@DantyElla, the Guest Lectures will be at either one of the 2 classroom buildings that your Sims go to classes in. Around the Quad area (the area with your school's statue) there are 6 clickable buildings: 2 dorms, 1 Student Commons, 1 sports arena, and 2 classroom buildings.  Just check either of the 2 classroom buildings between 5pm and 7pm (not sure about weekends, but they are offered at least on weekdays.)  It if isn't time for a lecture, the option should be grayed out. This is also where your Sims can tutor others for money (be sure that you Sims has a high skill level or else the money earned is not worth the time spent) 

My Sim is at Britechester University right now, so here are some pictures of the buildings where you can attend guest lectures:

Building #1

Building #1 in relation to the central Quad and Statue, as well as the 2 dorms
