We’re told the films: GMOPSU. We know there are two theaters: east and west. And we know on a single afternoon, there will be a presentation in each theater at 1 2 and 3. Finally, we know that each film will be presented exactly once.
So how would we set that up? Maybe
East _ _ _ West _ _ _ With each of those slots being 1 2 3.
Now the rules: S is west. We don’t know what slot, but let’s put it next to the setup:
East _ _ _ West _ _ _ S
Same for rule number 2: U is east.
East _ _ _ U West _ _ _ S
Rule 3: M must be before O and P. Given that M has to come before two other films, we know that M has to either be in slot 1 in either theater (then O and P could be in any of 2 or 3 slots) or M could be in slot 2, and then O and P have to be in slot 3 east and west, or west and east.
Rule 4: U must be before G. We already know U is in East. We now know it can’t be in slot 3, so it is either in slot 1 or 2 of east.
That’s about it for the setup! I would dive in to the questions at this point. Did you have trouble with any in particular?

No - I got all the questions right. It just felt like it took me too much time on the set-up. What are these games called so I can study more? Thanks much for your help. I'm down to 12 days...

I'm confused on why O would be in slot 3 instead of S? Since according to the rules S is in the West theatre.
