<p>Hey guys, I had class today and I had no idea on how to use it, and I lost out on a lot of potential points. And I need help!! So when the professor posts a question, you just press the letter button and press send? will know your answer sends if the screen turns back to “Ready?”</p>
<p>Also, how do you know if you get it right? I got a checkmark next to my answer. Does that mean it’s right?</p>
