# How do you stack up?

Above are the class averages for 3 9th grade Algebra classes.

When you get back a Math test test your score isn’t that important. What’s more important is how you did compared to the rest of the class. If you got a 90 and the class average is 70 you rock! If you got a 90 and the average is 95 not so much!

# Why Open Book Exams? The Answer is NOT in the Book

The answer is **NOT** in the book!!!! I found this out the hard way in college as some profs allowed us to use our books during engineering exams which only help if you know how to do the problem solving. I never took the Professional Engineering (PE) exam but you can bring any books you like!!

Now as a prof, I allow open book/notes and design exams to inspire critical thinking and metacognition (awareness and understanding of one’s own thought processes). Samples will be posted after Monday’s final exam.
