Hello - One’s prior knowledge and experience will significantly impact the amount and type of exam preparation that may be required to pass the exam. CertMaster may be used as a stand-alone learning tool, or as a companion tool in combination with other training and study materials. The CertMaster learning platform is adaptive and will always adjust your path through the course automatically based on what you already know and what you still need to learn. The Additional Learning page for each question goes into greater depth as well. Every CertMaster course has been given the CompTIA Approved Quality Content (CAQC) seal by ProCert Labs. All products with CAQC approval have undergone a rigorous review to ensure that the content covers all of the published exam objectives. If you believe that there were specific Network+ exam objectives not covered in the CertMaster course content, please submit an online request (https://s5.parature.com/ics/support/default.asp?deptID=15074) with the ticket type CertMaster Content and we’ll be glad to follow-up with you.
