1.What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake. How will you remember what to do in future tests.
My first mistake was not making the number in lowest terms.
My second mistake was not reading the questions right.

Rewrite 2 questions that gave you difficulty with different numbers.
