Dominate GMAT Verbal - Comprehensive GMAT Verbal Prep Course
Per-criterion
The course covers all AZ-900 exam domains across approximately 7.5 hours of video: cloud concepts (IaaS, PaaS, SaaS, CapEx vs. OpEx), core Azure architecture (regions, availability zones, resource groups), compute, networking, storage, databases, identity and access management, security and compliance, governance, and Azure pricing models. Matt Ouellette at Packet Pilot noted it "had well built demonstrations and labs to follow along with your free Azure account or built in labs" and "did a good job at giving you a high level overview of AZ-900." The course is updated for January 2026 exam revisions and includes Version 4.0 with re-mastered audio and updated slides. The primary content critique across sources is that 7.5 hours covers the breadth of the exam at a necessarily high level — every reviewer who mentioned it recommended pairing the course with Microsoft Learn or a dedicated practice-test package to fill the gaps the compressed runtime cannot cover in depth.
Scott Duffy is consistently described across all analyzed sources as a clear, approachable instructor who excels at making cloud concepts accessible to both technical and non-technical learners. Reddit user WayneH_nz called him "an AMAZING trainer." The Javarevisited article by javinpaul ranked Duffy's course first among AZ-900 options specifically because he "explains Azure cloud concepts in an easy-to-understand way" with "real-world examples, hands-on exercises, and quizzes." Shafath Ahmed on Medium wrote that Duffy "does a pretty good job explaining the Azure fundamental contents." No reviewer across the 26 opinions analyzed raised concerns about teaching quality, pacing, or clarity — the instructor dimension is the strongest scoring element of this course.
The course sells on Udemy during frequent sales for approximately $12–$15, which Reddit users across r/cscareerquestions, r/sysadmin, and r/AZURE cite as one of its key selling points. User The_Real_Tupac on Reddit noted "it regularly sells for $12," and user geekinuniform suggested "spending $12 for the Azure course" specifically to learn cloud terminology. For that price the course includes 7.5 hours of video, a 24-page PDF study guide, downloadable audio files for offline listening, slides, and a 50-question practice test — a bundle that multiple reviewers described as exceptional value at the sale price. Lifetime access and free updates that track exam revisions (including the January 2026 update) further strengthen the value proposition.
The course includes one 50-question practice test, which reviewers consistently describe as a useful baseline gauge but insufficient standalone exam preparation. Reddit user flam3throw3r from r/AzureCertification specifically recommended pairing it with Tutorials Dojo practice tests for more exam-representative questions. User extra_specticles on r/AZURE described watching the course first, then taking practice tests from an external source to identify weak areas. The cyber4noobs.com guide noted that optional lab add-ons are available separately but not included in the base course price. The practice material is proportionate to the course's 7.5-hour scope — it functions as orientation rather than the comprehensive drill-and-review system that Udemy's dedicated practice-test packages offer.
The AZ-900 is a fundamentals-tier exam with a passing threshold of 700/1000, and every reviewer who reported an outcome after using this course passed, many on their first attempt. Reddit user jpanda206 on r/AZURE studied for "about 3 weeks with Udemy and Microsoft Learn" and passed with a score of 790. Shafath Ahmed on Medium passed after approximately two weeks of preparation using Scott Duffy's course alongside Microsoft CLX and Microsoft Learn, completing the exam in 20 minutes of the allotted 45 and scoring above 90% on final practice runs. The cyber4noobs.com reviewer passed after one week of intensive daily study. No reviewer in the analyzed set failed after completing this course, though most credited a multi-resource approach rather than this course alone.
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.
