CISSP Certification Exam Prep Course
Per-criterion
IELTS Academic Test Preparation
With 80+ hours of material across roughly 100 short videos and five modules, the course covers listening, reading, writing and speaking systematically, using authentic IELTS-style exercises built by an official IELTS testing centre. Learners repeatedly praise the volume and quality of practice and the clarity of explanations. The content is comprehensive enough to serve as a primary preparation resource for many test-takers.
The course is written and presented by experienced UQ English-teaching staff with backgrounds in linguistics and TESOL. Learners describe the presentations as clear, professional and easy to follow, and value the credibility of a top-ranked university and IELTS centre behind the material. There is no single star instructor; the strength is institutional rather than personality-driven.
The course is free to audit with full access to all 80+ hours of material during the access window, which is exceptional value given the price of commercial IELTS courses. A paid verified track adds a certificate and some additional materials. The main limitation is that free access expires after the course window, so you lose the materials once it ends.
This is the course's real weakness and the most consistent criticism. The interactive exercises and practice tests are excellent, but the two productive skills are under-served: there is no live speaking practice or expert speaking feedback, and learners report the writing/essay feedback mechanism (largely peer-based) is inconsistent and less helpful than hoped. You must supplement Speaking and Writing with an external tutor or partner.
Because the exercises closely mirror the real exam and the strategies are test-specific, the preparation transfers directly to test day. Multiple learners credit the course as their primary resource for achieving strong band scores, including Band 8. For Listening and Reading especially, the practice maps almost exactly onto what the test requires.
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.
