Most titles contain review quizzes throughout the course and many also include a comprehensive final test. Each quiz can be taken twice but the final test can only be taken once. A final score of 90% or higher on the final test allows the student to print off a personalized Certification of Successful Completion. If a score of 90% is not attained on the final test, the course can either be re-purchased or, if the student feels confident, the re-Certification Test can be purchased which allows them to take the final test without having to complete the entire course and quizzes again.
Each course also has an expiration time which begins from the date it is purchased. Please make sure to set aside enough time to devote to completing the course before purchasing.
