ASTRONOMY TEST CORRECTIONS
You have the opportunity to earn extra points towards your FINAL ASSESSMENT
GRADE. This will be entered in a separate column from your actual test grade. In
order to do this, you need to:
1) See me for the key to find out which questions you missed
2) For each question that you missed, answer the question given below. (I am
not returning the actual test back to you since this is an exam used for
multiple classes over multiple school years.) You must not only answer, but
also support each question using full sentences (at least 2-3).
3) Turn in your answers with the answer sheet from your test
4) I will give you ½ point for every 1 test correction you make. You may not
earn more than 70%.
