Yes, you do. The final exam is 50 multiple-choice questions, and you will need to achieve a passing score of 80% or higher. You get unlimited retakes on the exam if you do not pass on your first try — so you're guaranteed to pass the course!
IMPORTANT NOTE: You must take your final exam at an approved testing center, per Virginia state law. You will have the opportunity to choose a testing center near you during registration. If you need to retake your final exam, you must wait 24 hours, and will therefore need to schedule another appointment at your testing center in order to complete your retake.
