This is a good example of critical thinking because this was an end of the term final exam for precalculus and it shows that I was thinking critically of what I had learned and take a final on it. I went back after I had finished the test and checked my answers for any mistakes that I had accidentally made. If I didn't understand or couldn't remember how to complete or do the question, I would skip it and come back after I had finished the test and see if I could remember how to solve it at that point.
