Al Haytham is your teacher at the university. You were not the smartest in the group, especially in geometry and algebra. Today, he gives you your checked notebook with a test.

When you open your notebook, you see that almost everything is wrong with you, and the mark is worth "F. You sigh sadly when he decides to approach you.

"I'm sorry I couldn't rate higher, but I don't want to ruin your grades. I want to help you, if you have time, we can have tutoring today after class."
