I first took the preassessment and barely passed it. Then, my course instructor sent me some material to review for the OA. This is what I used to pass:
Quizlet (Great help for the preassessment) - https://quizlet.com/1075050836/d685-practical-applications-of-prompt-flash-cards/
Comprehensive Study Guide - https://drive.google.com/file/d/1aOBUaLjrjE1PV8K8JPL7820f25IvA2Ao/view?usp=sharing
Kahoot - The Kahoot my instructor sent me expired but it was a non timed Kahoot of about 42 questions.
Course Material:
Course Practice Test A and B: Would go through both tests and read why each answer was right making sure to understand everything clearly. If I thought another answer would be right, I would select it to see why did not fully understand why an answer was right, I would select another answer on the question to see the explanation on why it was wrong.
Section Tests: Would go from section 1 to 4 starting with the Test A for each section then go back to Section 1 all the way to Section 4 doing the same process but with Test B. Would do the same process that I did on the course practice test of reviewing each answer to confidently understand why the answer was correct.
I would also practice these questions whenever I had the opportunity, whether I was eating or doing some other mundane task.
After about two days of doing this, I took the OA and got Exemplary. My tip if I had to do this again is to review the quizlet to pass the preassessment 1st try. When I got the email is when I got the study material so hopefully your instructor sends you a kahoot to study. Pretty easy and can be done in two days if really focused. I was kind of worried that I needed to know everything to pass but this is all it really took.
