WOMAN: Because we're sisters, we end up being strongest in the point where the other person's weakest.

WOMAN: Yes.

WOMAN: So I'm not good at math. But both of them are amazing at math. So they help me with my math. If I don't know what to do, I just come and I sit beside them. I'm like, I don't know how to do this. And they help me figure out how to do it, basically, so I don't have as much problem with it.

WOMAN: Yeah, and also, even deeper than that is that sometimes, we'll get different problems wrong on the same exact test, but we'll get the same percentage. But even that way, we can compare answers and say, oh, how did you get that, and do you know why I got this wrong, and stuff like that. So it kind of helps have someone to bounce that back off of.

WOMAN: Like they said before, we quiz each other. So I'll read my notes, and then I'll come downstairs. And I'll say, OK, read my notes off. Ask me a question off what do my notes say and see if I can answer it right.

WOMAN: Yeah. And it helps to teach it to a person, because if you're able to teach it to a person and they understand it, then you know you have it. And then you help them learn something that they might not have understood.

WOMAN: I think the main thing for me is I love to get my test back to study for final exams or anything like that. It's helpful, because you don't have to make up flash cards or anything. You just give the person the test, and they can see what you got wrong, so they'll ask you special questions about that. Like can you tell me what X, Y, and Z means? Or why did you get that wrong? And like Lexie said, when you're actually able to teach something to someone, that means you totally have it down. So that's usually where we try to get to. We have an audience, so we use it.
