Learn about general computer science concepts
Assignment: You will be given an exam and you will solve them on the board.
Mr. Cusack will assign you to a team.
You will need to do 10 questions on the Board at a time.
As you determine each answer, verify the answer with Mr. Cusack.
If you answer is wrong or you do not know:
You are allowed to ask Mr. Cusack questions.
Mr. Cusack may ask you to explain your answer.
Once done with all 4 groups of 10 questions,
you will need to turn them into google classroom.
(your group will be 3 or 4)
