Are you tired of furiously scribbling notes in your classes as the teacher talks a mile a minute? Aren't you afraid that you'll miss writing something down—something important that will get you on the final exam? My friends, you need to change the way you take notes in
class. Today, I'm going to show you the PenCam, a cool, new camera that sits on the end of your pencil. Forget writing everything down.
This powerful little camera can capture every moment of every lecture for you. You can just kick back and relax during your classes. Let
the PenCam do all the work for you.
