The way I respond when I don't know the answer to a question is to find out who does know the question, and also to allow the person who does know the question to help me answer the question. So when that question comes back around, I can answer the question with proficiency, with expertise, so I wouldn't have to go back and go ask that person to explain to me the answer to this question all over again. It's kind of like when you ask one of your friends in class that understands the equation better than you. You ask them, can you explain this equation to me? And then they explain it in a way that you can understand it. Then now you can apply that to the test, apply it to whatever exam that you have the next day, because you already understand it because someone explained it to you.
