@newapplicant, I agree with @berkeleymom4. Take the organized tours, but if you have time, poke around too. My son even met the ME department head when he was still deciding. I’d do the housing tour IF where you live is more important than who you live with. I am BIG fan of the engineering living learning community because it’s all freshmen engineers living together. Cerro and PCV are definitely nicer, but there are less freshmen. So, if it’s LLC, you can skip the tour as it’s Sierra Madre in the Red Bricks. If the building itself is more important to you, take the tour. Have fun!
