I don't get you, buddy. If you are talking about the Intro worksheet, just scroll up. There is nothing like an answer worksheet in that document. As you type the right entry, you will see a smiley if correct, otherwise, a sad smiley, and the marks will start ticking accordingly. The final score is available on the last worksheet, 97-120.
Forgot about that attachment, download the new attachment which I did this morning after your comments.
