Hello, I am just wondering what it means in my study plan when it says Test 1 CARS workbook..?

I looked in the "study plan components" and it says odd-numbered test. So, do I do only the odd-numbered passages in the first test of the ExamKrackers 101 CARS workbook? Or The odd-numbered questions of the first test of the workbook? Or all of the questions..?

Thank you
