CISSP Certification Exam Prep Course
The course covers all eight CISSP CBK domains as defined by (ISC)²: Security and Risk Management, Asset Security, Security Architecture and Engineering, Communication and Network Security, Identity and Access Management, Security Assessment and Testing, Security Operations, and Software Development Security. Chapple structures each domain systematically, beginning with foundational concepts and building toward the scenario-based reasoning that the CISSP adaptive exam rewards. Learners consistently report that Chapple's lectures decode the conceptual density of the Official Study Guide and reframe key ideas in ways that make the most challenging domain content — particularly risk quantification, cryptography, and PKI — accessible without oversimplifying. His background as both an active security practitioner and academic means domain coverage contextualises theory within real organisational security decisions rather than presenting isolated facts. The main content gap noted by experienced candidates is the volume of built-in practice questions. The video instruction is comprehensive, but most successful CISSP candidates pair it with a dedicated practice test resource such as the Official (ISC)² CISSP Practice Tests, also co-authored by Chapple, or a third-party platform such as Boson ExSim.
Mike Chapple, Ph.D. holds the CISSP, CISM, CySA+, PenTest+, and Security+ certifications and serves as Teaching Professor of IT, Analytics and Operations at the University of Notre Dame's Mendoza College of Business. He co-authored the Official (ISC)² CISSP Study Guide (now in its tenth edition) and the Official (ISC)² CISSP Practice Tests, and has written more than 50 technology books and produced over 150 Udemy and LinkedIn Learning courses. His teaching style transforms dense regulatory and conceptual material into clear, structured instruction without sacrificing technical accuracy. Students consistently describe him as "calm," "methodical," "patient," and "one of the best technical instructors on any platform." His explanation of the CISSP managerial mindset — thinking as a security manager rather than a hands-on technician when selecting exam answers — is cited by numerous first-time passers as the single most valuable insight they received from any study resource. CertMike community testimonials note that his course is "far more helpful than a $2,000 boot camp."
At Udemy's standard promotional pricing of $15–25 (promotions occur near-weekly), the course represents exceptional value relative to the $749 CISSP exam fee and the $2,000–$3,500 price range of in-person boot camps. Multiple learners in Reddit's r/cissp community explicitly describe abandoning boot camp registrations in favour of Chapple's course after comparing outcomes reported by peers who used each approach. The course pairs naturally with the Official (ISC)² CISSP Study Guide that Chapple co-authored, creating an integrated study ecosystem where book and course reinforce each other at a combined cost still well below most single-day boot camp fees. For a credential with transformative career impact — median salaries for CISSP holders exceed $120,000 in the United States — the cost-to-certification-value ratio is unusually favourable.
Multiple learners report that the CISSP preparation process through Chapple's course produced a materially more comprehensive view of organisational security than their prior professional experience had provided. The eight CBK domains together constitute a breadth-first survey of enterprise security governance, and working through them systematically often surfaces gaps in candidates' understanding that were invisible from within their specialised day-to-day roles. Security professionals in roles such as security architect, CISO, security manager, and senior analyst specifically credit the course with reinforcing enterprise security governance frameworks — NIST CSF, ISO 27001, SOC 2 — in ways that improved their day-to-day security decision-making well beyond the exam context. The risk management and security assessment domains are cited as particularly rich in immediately applicable content.
Mike Chapple maintains a companion platform at certmike.com where he facilitates free 90-day CISSP study groups. These structured group programmes — featuring weekly schedules, live Q&A webinars, and community forums — are cited by multiple graduates as a significant differentiator that addresses the primary failure mode of solo CISSP self-study: losing momentum across the months-long preparation period. Within Udemy, Q&A response times are variable, a structural issue across the platform rather than specific to this course. The CertMike study group fills much of this gap. Learners seeking broader community discussion also gravitate toward r/cissp on Reddit, which frequently recommends Chapple's resources as a primary study tool. The slight fragmentation between Udemy Q&A and CertMike community is the main friction point noted by learners.
Comprehensive GMAT Prep: Self-Study Guide to GMAT 700+
The course is positioned as a consolidated self-study strategy guide rather than a full content syllabus: it teaches how to plan a GMAT preparation, how to attempt questions, and how to track progress, rather than re-teaching every quant and verbal concept from scratch. Reviewers describe it as covering "all important aspects of the GMAT exam in an easy to comprehend manner," and the standout asset is a specially designed MS-Excel GMAT Analysis Tool plus consolidated revision notes. The honest limit is breadth — it is a strategy and planning layer, not a comprehensive concept course, so a true beginner will need separate material to actually learn the maths and grammar.
The instructor's credibility rests on a concrete, verifiable claim: a GMAT 740 (Q50, V40) on the first attempt achieved through self-study. That is a strong, top-percentile result and it gives the strategy advice real weight, because the whole course is essentially "here is exactly what I did." The teaching philosophy — "if I was able to crack the GMAT through self-study, anyone can" — is encouraging and the test-day strategy insights are the part learners single out as genuinely useful. The deduction is transparency: the instructor's full name and broader teaching track record are not prominently published, so you are trusting one person's score story rather than an established prep brand.
This is the course's strongest dimension. It is explicitly priced "at the lowest possible price" and is regularly available very cheaply or via free coupons, with lifetime access and Udemy's 30-day refund. For the cost of a single coffee you get a structured self-study roadmap, an Excel tracking tool and revision notes from a 740 scorer — a tiny fraction of what Target Test Prep, Manhattan Prep or e-GMAT charge. The fair caveat is that the low price reflects scope: you are buying a plan and tools, not thousands of practice questions, so the real cost of your prep is this plus the official GMAT material you still need to buy.
The weakest area and the one most likely to disappoint buyers who expect a question bank. The course includes some solved questions to illustrate the attempting strategy, but it is not a high-volume practice resource — there are no full-length adaptive mocks and no large bank of original problems. Its own design assumes you will do your heavy practice in the Official Guide and GMAT Official Practice Exams; the course's job is to tell you how to use them efficiently and track your weak areas with the Excel tool, not to be your practice source.
The realistic value proposition is structure and efficiency rather than a guaranteed point jump. Learners credit the test-day strategy and the self-analysis tool with helping them prepare smarter, and the 740-scorer framing maps the plan onto a genuinely high outcome. But because the course supplies little practice and no full mocks, any score gain depends almost entirely on the learner pairing it with official material and doing the timed reps — the course is the map, not the miles.
