 Well, there's classes like A-term and B-term. Okay. I think they're like six-week courses, which I know that's more than 30 days. But I'm just saying there's different options. Like you don't have to buy it permanently, and you can rent it for shorter or longer. And so that can make it a little cheaper. And why did you choose Northwestern? Because they gave me the most money. What does that mean? Like without living on campus, my tuition is like paid.
