Chemistry I ADV: Unit 7 Test - States of Matter and Gas Laws - Make-up Points
You can make up half of the points that you missed on the test by doing the following:
1) Place a check mark next to the numbers of the questions below that correspond to the numbers of the questions or
problems on which you did not make the maximum points on the Unit 5 test. For example, problem #29 on the Unit 5
test was worth 10 points. If you only made 9 points on #29, then you must check #29 on this make-up.
2) On the 1st night or weekend that you get this practice test, write the answers to the questions or solve the problems for the
numbers that you’ve circled on a separate sheet of paper.
3) Bring your answer to Mr. Tedder to review after school on the following school day.
4) On the 2nd night or weekend after you get this practice test, make all the corrections. You MUST get ALL the answers
to the required problems CORRECT or you will get NO credit.
5) Staple this sheet to the back of your answer sheet(s) and turn in the answers or problem solutions on the 2 nd school day
after you get this practice test.
