AZ-104 Microsoft Azure Administrator — Complete Exam Prep vs Dominate GMAT Verbal - Comprehensive GMAT Verbal Prep Course

The course is aligned to the five official AZ-104 exam domains: managing Azure Identities and Governance (Azure Entra ID, RBAC, subscriptions, resource groups), implementing and managing Storage (Blob, File, SAS tokens, lifecycle policies, backup), deploying and managing Compute Resources (virtual machines, scale sets, App Services, containers), implementing and managing Virtual Networking (VNets, NSGs, load balancers, VPN gateways), and monitoring and maintaining Azure Resources (Azure Monitor, Log Analytics, backups, alerts). The V6.0 May 2025 update added practice exam content, refreshed the Microsoft Entra ID modules, and expanded Azure Web Apps coverage. The curriculum totals approximately 17.5 hours of on-demand video — substantial enough to cover every exam objective at meaningful depth without the padding that inflates cheaper courses. Eleven downloadable resources and a free study guide PDF supplement the video content. The bonus "last-minute exam cram" is a three-hour focused review session specifically praised by learners who used it the day before their scheduled exam. The content limitation most frequently cited by learners is a structural consequence of Azure's continuous update cycle: Microsoft regularly changes the Azure portal interface, and some lab walkthroughs demonstrate configurations in interface versions that no longer match the current portal. Learners report that the underlying concepts remain accurate — the lab steps just require adaptation to the current UI when steps do not match.

Scott Duffy is a software architect and Microsoft Azure MVP (Most Valuable Professional) with the MVP award held continuously from 2022 to 2025. He has accumulated 1.5 million total students across his Udemy catalogue, making him one of the platform's most-enrolled cloud computing instructors. His background as a software architect rather than a pure trainer gives the course a practitioner's perspective — he explains architectural trade-offs and design rationale rather than simply narrating portal clicks. Learner feedback consistently describes Duffy as "well organized," with one opencourser.com review noting he "clarified a lot of issues in the first few lectures" in a way that set a strong conceptual foundation before moving into complex topics. His willingness to update the course repeatedly (six major versions, with V6.0 released May 2025) signals genuine investment in keeping the material current — a differentiator in a certification niche where many courses are recorded once and left to age. The criticism that appears across multiple three-star reviews is pacing: the course assumes some prior familiarity with cloud concepts, and learners who are new to Azure entirely may find some modules progress faster than they can absorb. Scott's AZ-900 (Fundamentals) course is the recommended prerequisite for those without prior Azure exposure.

The course lists at $119.99 but Udemy's promotional pricing structure means the effective purchase price is consistently $14–$15. At that price point, 17.5 hours of video plus a full practice exam, downloadable resources, a study guide PDF, and lifetime access with ongoing updates represents outstanding value in the certification preparation market. The AZ-104 certification itself costs $165 per exam attempt. A course that equips learners to pass on the first attempt — as documented by multiple first-attempt pass reports in blog coverage — has a total cost (course + exam) of approximately $180, compared to failing the exam once and retaking it ($330 total). The course's value calculation therefore extends beyond the purchase price to include avoided retake costs. The included practice exam was highlighted as a significant value addition in the V6.0 update. Prior versions required learners to purchase practice exams separately; having both preparation content and assessment in a single purchase at this price is notable. Learners who want more practice exams beyond the included set frequently cite Whizlabs or MeasureUp as well-regarded supplements at additional cost.

The AZ-104 certification maps to the Azure Administrator associate role — a job title with significant market demand across mid-size and enterprise organisations that have adopted Azure as their primary cloud platform. The course is therefore preparation for both a certification exam and a real job function. Multiple learners in blog coverage describe the course as directly applicable to their current administrative responsibilities: understanding the concepts in the networking module (VNets, NSGs, VPN gateways) is immediately useful for administrators managing Azure environments in production. The monitoring module (Azure Monitor, Log Analytics) addresses skills needed to maintain production systems rather than pass exam questions in isolation. The Malith Ileperuma documentation of passing the AZ-104 in fifteen days (studying four to six hours per day) while combining Duffy's course with hands-on Azure labs demonstrates the study pattern that produces the best outcomes: the course as conceptual framework, supplemented by actual Azure portal practice using Microsoft's free labs. Learners who only watch the videos without deploying resources in a real Azure subscription consistently report less confidence in exam and post-certification scenarios.

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.
