CISSP Certification Exam Prep Course vs Magoosh ACT Prep

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.

Magoosh ACT Prep covers all four ACT sections — English, Math, Reading, and Science — across 250+ video lessons, with optional Writing content available. The course has been updated for the Enhanced ACT format, and reviewers at EduReviewer and Sojourning Scholar confirm that the content accurately reflects current exam structure and difficulty. Lead instructor Erika holds 99th-percentile scores on the ACT, SAT, GRE, and GMAT, lending strong credibility to the instruction. A critical note from the PrepScholar comparison blog is that some video lessons were found to contain errors in ACT scoring system information, which slightly offsets the otherwise strong content quality score.

The teaching team at Magoosh is consistently described as "personable and clear" by Test Prep Insight reviewers, and students specifically cite strategy-first instruction that goes beyond memorisation — teaching how to "find the main idea quickly and beat the clock" and providing "tips and tricks to improve overall score." Lead tutor Erika's 99th-percentile credentials are prominently featured. The main criticism is the whiteboard-style video format, which multiple reviewers describe as slightly "on the boring side" despite being instructionally sound. The PrepScholar comparison also flagged specific lesson errors in earlier versions of the course, which Magoosh has since addressed in updated modules.

Magoosh ACT Prep is widely regarded as the best-value ACT prep option in the industry. At $99–$129 for 12-month access — or as little as $79 for a one-month plan — it costs roughly one-tenth of traditional private tutoring ($1,000+) and significantly less than Kaplan ($449–$1,000+) or Princeton Review ($799–$1,599). The 82,000+ students served and a backed +4 point score improvement guarantee (or full refund) are strong signals of institutional confidence in the product. Both Test Prep Insight (9.0/10) and EduReviewer (4.6/5) cite value as Magoosh's single strongest dimension.

The course includes 1,500+ practice questions and four full-length ACT practice tests, each with detailed video and text explanations for every question — a distinctive feature not found in all competitors. Customisable practice drills allow targeted section work. The main limitation, flagged by both Test Prep Insight and the PrepScholar comparison blog, is that the four practice tests are generated from the same question bank rather than being fully unique exams, creating potential overlap if a student cycles through all four. Princeton Review offers 11 simulated ACTs to Magoosh's four, making Magoosh thinner on full-test volume for students who need repeated full-exam simulation.

Magoosh's own review page documents seventeen score improvement entries from students who reached final scores of 28–34, with individual improvements ranging from +1 to +12 composite points. The most commonly reported gains are +3 to +5 points. One student improved from 28 to 33 using Magoosh exclusively. The company reports helping more than 82,000 students, and their score improvement data page (Magoosh Schools Blog) shows that users outperform national averages when they commit 30–40 hours of preparation. The guaranteed +4-point improvement for students scoring under 30 is a meaningful benchmark backed by a refund policy.
