Reflect on your CSTs

History- Basic, Proficient, Advanced? What do you wish you studied more? Do you need to suggest to your teacher to focus more on something for next year…..

If you missed a test for APs— you can still study… For example— MATH- write all the formulas you may need

English-

Math-

Science

Write what you HONORABLY deserve out of 50 and check them in
