Dear Students, 

Thank you for taking Practice 1 at College Board BlueBook App. Unfortunately, as an Educator Account, I cannot access your data, nor can I see the questions in the practice test. Please share your score with me either in person or by email, so that I can keep track of your progress:)

Please save Practice 2 and 3 for our Mid- and Final- exams in the Spring semester. As you are not allowed to skip English sessions in the practice test, I will ask you to finish the English part at home, and come to school to finish the math part in class for the future Mid- and Final- exams.

Please take screenshots of the questions you want me to explain, and upload them to a shared Google Drive. I can use that to help go over next week.

Homework:-ET 14: Lines
Next week will be the first week of the Spring Term. Please bring your textbook, and we will start Ch. 15. Interpreting Linear Models.

Warm regards,

Ms. Li
