Microsoft certification exams are a great way to build your resume and let the world know
about your level of expertise. Certification exams validate your on-the-job experience and
product knowledge. While there is no substitution for on-the-job experience, preparation
through study and hands-on practice can help you prepare for the exam. We recommend
that you round out your exam preparation plan by using a combination of available study
materials and courses. For example, you might use this Exam Ref and another study guide for
your "at home" preparation, and take a Microsoft Official Curriculum course for the classroom
experience. Choose the combination that you think works best for you.
