All-In-One study guides contain information pertinent to the preparation for various examinations. The focus of many of these exams is IT-related – including database administration and cyber forensics – but topics such as human resources and business analysis are also covered. Published by Mcgraw-Hill Education and written by area experts and educators, these texts are designed to provide students with comprehensive factual information, learning objectives, examples of exam questions, and tips and tricks for completing the exams themselves. Some also contain large collections of complete practice exams, which can be used to prepare students for different exam conditions and formats. In addition to being resources for students, these texts also function as useful references for current professionals to use on the job.
