AZ-104 Microsoft Azure Administrator — Complete Exam Prep vs GRE Complete Prep: How to Score 330+ for Top Grad Schools

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 all three GRE sections — Quantitative Reasoning, Verbal Reasoning, and Analytical Writing — across 27+ hours of on-demand video, with 400+ practice questions and downloadable resources. Reviewers describe the content as systematically structured, building from foundational concepts (fractions, exponents, roots) up through advanced topics. The 2024 update added 30+ new videos reflecting GRE format revisions. The main limitation noted by critics is that content is almost entirely video-based with no dedicated offline summary PDFs and some missing quiz answer options.

Dr. Gerald Day Richardson holds both an MD and an EdM from Harvard and personally aced the GRE. Students consistently praise his calm, clear teaching voice and ability to demystify difficult concepts. Testimonials describe him as "thorough, covering so many concepts in great detail" with a "soothing instructor voice." His approach — building from absolute basics without assuming prior knowledge — is singled out repeatedly as what sets this course apart from others.

The list price sits around $84-99, but the course is almost always on Udemy sale between $15-25, with lifetime access and a 30-day money-back guarantee. At sale price, 27+ hours covering all three GRE sections with 400+ practice questions represents strong value versus Magoosh ($149+/year) or Manhattan Prep ($249+). Independent reviewers confirm Udemy GRE courses offer "incredible bang for your buck" at their typical sale price. The trade-off is that — unlike premium platforms — this course lacks full-length adaptive mock tests and vocabulary tools.

The course includes an active Q&A forum, and student reviews note the instructor responds to doubts — one reviewer specifically praised that "the tutor goes an extra mile to reply quickly to your doubts." However, support is limited to the Udemy Q&A system; there is no live tutoring, community forum outside the platform, or direct messaging. For a self-paced $15-25 course this is reasonable, but learners needing real-time feedback should consider supplementing with a dedicated GRE community like r/GRE or GregMat's Discord.

Multiple verified students report meaningful score improvements after completing the course. One student credits it with helping her "gain admission to my dream graduate program," and another says he "finally beat the 160 barrier." A non-native English speaker reports scoring "so much higher on the real exam" after completing the verbal and writing sections. The caveat from independent analysis is that the course works best as part of a broader study plan supplemented by official ETS PowerPrep practice tests — the teaching is strong, but the course alone may not be sufficient for students targeting 330+ without additional timed practice.
