CISSP Certification Exam Prep Course

Content quality4.7 / 5

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.

Instructor4.9 / 5

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."

Value for money4.8 / 5

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.

Real-world applicability4.6 / 5

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.

Support4.2 / 5

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.

Magoosh GRE Prep

Content quality4.1 / 5

Magoosh provides 290+ video lessons covering Quantitative, Verbal, and Analytical Writing, plus 1,600+ practice questions — 160 of which are licensed official ETS problems, making Magoosh the only US GRE prep company with access to these materials. Independent reviewers at Test Prep Insight confirm the practice problems are "a close match for the real GRE" and that it would be "hard to decipher real GRE problems from most of Magoosh's mock problems." The main content criticism is that hard-level Magoosh quant questions can exceed actual GRE difficulty, and the curriculum occasionally presents problems before the relevant concepts have been fully taught in the video lessons.

Instructor4.2 / 5

Tutors Chris Lele and Mike McGarry — the primary Magoosh GRE instructors — are recognized as experienced GRE educators who know their material deeply and present it clearly. GRE tutor Vince Kotchian (15+ years experience) specifically called them out as experienced teachers with strong instructional abilities. The consistent criticism is the delivery format: PowerPoint-style slides with voiceover rather than an instructor on camera, which multiple reviewers describe as "not the most engaging" and less polished than Kaplan's dynamic whiteboard format.

Value for money4.6 / 5

At $149 for one month or $179 for six months, Magoosh is consistently described as an "absolute steal" and "bang for the buck" by independent reviewers — especially compared to Kaplan ($599), Manhattan Prep ($599+), and Princeton Review ($449+). The +5 point score guarantee with a full refund option (verified by actual users who received refunds) and a 7-day no-questions-asked return window add additional low-risk appeal. Test Prep Insight calls the pricing "an absolute steal," and EduReviewer assigns value-for-money a 4.5/5 score. The Live Classes add-on at $499 is seen as significantly less attractive value.

Practice material4.0 / 5

Magoosh provides 24/7 email support from GRE tutors, with response times reported consistently within 24 hours and often faster. Top Consumer Reviews (June 2026) notes customers report "getting feedback on their questions super fast and the responses are super helpful." The platform also includes in-app contextual help, score predictor tools, and links from each question to relevant lesson videos. The limitation is the absence of live chat or phone support — communication is email-only — and no private tutoring is bundled in the standard plan. Live class sessions (extra cost) add real-time interaction but are excluded from the core subscription.

Score improvement4.0 / 5

Magoosh reports an average student score increase of 5–6 points and a 5-point improvement guarantee. Verified reviews on gre.magoosh.com show students reaching scores of 322–335, with one student improving from 310 (157Q/153V) to 324 (165Q/159V). EduReviewer notes that 20% of Magoosh users score in the top 10%. GRE tutor Vince Kotchian's honest caveat is that Magoosh "is best for students in the middle who want structure and are okay with a score below 320" — those targeting 165+ per section may find the question difficulty ceiling insufficient for their goals, particularly on the quantitative side.
