The CBP test is divided into three main areas, which also differ in their time allocations: Logical Reasoning (81 minutes), Experience Record (60 minutes), and Writing (63 minutes).
The minimum passing score of the CBT exam is 70, and if you wish to retake it, you must wait for 6 months from the date of your first test.
You're allowed to use a calculator, scratch paper, and pencils during the exam, which you'll receive from your proctor (you can't bring your own items, though).
