CompTIA 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. Although there is no substitute for on-the-job experience, preparation through study and hands-on practice can help you prepare for the exam. We recommend that you augment your exam preparation plan by using a combination of available study materials and courses. For example, you might use the Training Kit and another training kit for your “at home” preparation, and take a CompTIA professional certification course for the classroom experience. Choose the combination that you think works best for you.
