Suggestions on studying geometry over the summer?
I'm currently a rising 9th grader that has decided to skip geometry over the summer. As of right now, I only have about a month to prepare. By the near end of the summer, I have to take an advancement exam which requires a minimum of an 85% to pass. Are there any suggestions on resources, (websites, apps, etc,) how to prepare, or any material, topics, or concepts I should really review, revise, or focus on in preparation for the exam?
(the curriculum is based off of is the big ideas math geometry textbook)
