Book Description
This book contains two high-quality practice tests of 80 questions each - with answers and explanations - to help you pass or improve your score on the free online Neo4j Certified Professional exam. * All questions are closely emulated from those currently found in the actual exam, so you'll not waste time on anything else. * Unlike the real exam, you'll know right away what questions you missed, and what the correct answers are. * Detailed explanations with external references for any possible choice, in each practice test question. * Quiz types distributed close to 50% multi-choice + 25% multi-select + 25% True/False. * Domains distributed close to the real exam: 40% Cypher + 30% Intro + 20% Modeling + 10% Developer. * Questions will test you on Neo4j version 3.x, but explanations will have updates on deprecated features and change history. Why not just trying again and again the free online exam, until I pass? * Because starting May 2020, you can try only once a day the real online exam. * Because the high number of multi-answer questions and the gotcha tricks may give you no idea what went wrong. * Because it is time consuming and you can easily get stuck at the same low scoring mark. * Because nothing tells you where and what you failed, and next time you will likely make the same wrong choices. * Because you can hardly improve without knowing what went wrong. * Because you may want to get a better passing score anyway, as long as it appears on your issued certificate. Same e-book as LIVE practice tests on Udemy: "Neo4j Certified Professional - Practice Exams".
