---------------BOB2--------------
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.
Well the first mistake I made was that I didn't go over my work after I finished it .
The second mistake I made was that I just guessed on the one for food . ( 12,13,14)
The third mistake I made was that I did number 16 wrong because I put the wrong numbers and I didn't put a word ratio .

Rewrite 2 questions that gave you difficulty with different numbers.
