Our courses are designed to provide you with all the knowledge and practice you need to pass the certification exam. The "Complete Course" includes all of the video lessons, quizzes, and study materials for the certification exam you are studying for. The "Practice Exams" course includes additional practice exams to help you prepare for the exam.

While you don't necessarily need to purchase both courses, we do recommend it if you want to maximize your chances of passing the exam on your first attempt. The "Complete Course" provides a comprehensive review of the material, while the "Practice Exams" course offers additional practice questions to help you build your confidence and identify any areas of weakness.

Ultimately, the decision to purchase both courses depends on your learning style, your familiarity with the exam material, and your confidence in your ability to pass the exam. We recommend that you carefully review the course descriptions and read reviews from other students to determine which course or courses will best meet your needs.
