CompTIA Security+ (SY0-701) Complete Course & Practice Exam vs Dominate GMAT Verbal - Comprehensive GMAT Verbal Prep Course

The course covers all five SY0-701 exam domains across 264 modules and 31 hours of video, spanning General Security Concepts, Threats and Vulnerabilities, Security Architecture, Security Operations, and Security Program Management. Reviewers on OpenCourser and Reddemy consistently praise the structured domain breakdown, acronym walkthroughs, and the alignment with official CompTIA exam objectives. The main content gap flagged by multiple learners is limited hands-on lab simulation — the course is predominantly lecture-based, which can make performance-based question (PBQ) preparation less thorough than the actual exam requires.

Jason Dion brings over 20 years of IT and cybersecurity experience to the course and is consistently described by reviewers as easy to follow, thorough, and amiable. OpenCourser reviewers Victor Cabrales and Mark Guillen both called out his clear explanations and acronym-focused teaching style as the course's standout feature. He holds CompTIA Platinum Partner status, and Dion Training's 4.6+ star network-wide rating across 2 million+ students reinforces his reputation as one of the most reliable certification prep instructors in the field.

The course is almost always available on Udemy for $13–$20 during the platform's frequent sales, a price point that Reddemy commenters repeatedly highlight as exceptional for 31 hours of content plus practice materials. One Reddemy user noted purchasing both the course and the separate practice exam set for approximately $13 each during a sale. At that price, Dion's course delivers one of the lowest cost-per-hour ratios of any paid Security+ preparation resource, with lifetime access and periodic content updates included.

Multiple reviewers who passed SY0-701 on their first attempt credit Dion's course as their primary preparation resource, including John T. (Medium), who passed in under two months with no prior cybersecurity background. The course's exam-focused framing maps tightly to Security+'s five domains and the career skills they represent — threat analysis, security architecture, and incident response. However, the lecture-only format and absence of hands-on labs mean learners entering cybersecurity roles will need additional practical experience beyond what the course alone provides.

Like most Udemy courses, learner support is limited to the platform's Q&A section — there is no live instructor interaction or direct email support. One Reddemy user flagged a structural navigation issue, noting difficulty jumping directly to specific domains without watching the course sequentially. Response times in the Q&A section are generally adequate for a high-enrollment course, but learners who need real-time feedback or personalized guidance will need to seek supplementary communities such as the r/CompTIA subreddit.

The course covers Sentence Correction (the "Big 6" grammar rules), Critical Reasoning, and Reading Comprehension across six-plus hours of instructional video. Learners consistently praise the clarity and structure — one student called the material "simple, straightforward and digestible" and credited Brett's "strategies and approaches for thinking quicker." However, the GMAT Focus Edition launched November 7, 2023 and completely removed Sentence Correction from the test, which was one-third of the classic verbal section. A course that still dedicates substantial runtime to a question type that no longer earns test-takers any points carries a content-currency problem that is structural, not stylistic.

Brett Ethridge is the course's strongest asset. A Duke University graduate and MA holder in International Finance, he has an instructor rating of 4.4 on Udemy across 3,199 reviews and is consistently praised for making complex verbal reasoning intuitive. Students describe him as having "fantastic teaching and amazing subject knowledge" and say the course "gave me tools to be confident with the test." Multiple students report 100–150 point score improvements they credit directly to his methods, and one debrief on GMAT Club singles him out by name: "The thing I enjoyed most about his style of teaching was that it was simple, straightforward and digestible."

At typical Udemy sale pricing (under $20 with lifetime access), Dominate GMAT Verbal is dramatically cheaper than the $147 standalone verbal plan on Brett's own DominateTestPrep.com or any full-platform competitor. Learners from the GMAT Club forum bought both this and a second Udemy verbal course for under $10 combined during a Black Friday sale, with one poster summarising the calculus as "Try it — it's virtually free." The honest offset is the GMAT Focus content problem: you are paying, however little, for a course that devotes significant time to Sentence Correction, a skill the current GMAT no longer tests.

The course includes worksheets for each of the six Sentence Correction grammar categories and reading comprehension and critical reasoning drills — adequate for reinforcement but not a high-volume question bank. Serious GMAT Club users consistently note that GMAC official practice tests are the only questions that truly mirror the adaptive exam, and neither this course nor any Udemy GMAT offering includes official GMAC material. For realistic GMAT Focus practice, learners must separately purchase the official GMAT prep software and question packs, making this course a teaching layer rather than a primary practice engine.

Where the course still lands well is on transferable reasoning skills. Critical Reasoning and Reading Comprehension — the two verbal question types retained in GMAT Focus — are taught rigorously, and multiple students report that Brett's structured approach to dissecting RC passages and CR arguments carried them on exam day. Student Georges Kazan (Quebec) specifically called out "Critical Reasoning tools were incredibly helpful," and another student described the experience as "like being handed a flashlight and a map" for an exam that had previously felt overwhelming. These skills also transfer directly to the verbal sections of the LSAT and GRE.
