AZ-104 Microsoft Azure Administrator — Complete Exam Prep vs Magoosh GMAT Prep

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.

Magoosh GMAT Prep covers all three GMAT Focus Edition sections — Quantitative, Verbal, and Data Insights — across 340+ short on-demand video lessons, and the curriculum was rebuilt after the Focus Edition replaced the classic GMAT on February 1, 2024. The Quant content is the standout: GMAT Club reviewers (Aabhash777, BelronMajes, GMATking94) repeatedly praise it for teaching from the basics and deriving formulas "from root level" rather than asking students to memorise. The consistent content weakness is Verbal, which multiple reviewers call "old," in need of "refurbishment," and structurally confusing with no continuity. Data Insights coverage exists but several students wanted more practice volume there given how central DI now is to the Focus Edition. The slideshow-with-voiceover format is instructionally sound but, as Test Prep Insight notes, "lacks production value."

The lessons are anchored by long-time Magoosh GMAT expert Mike McGarry, whose Quant explanations are described as crisp, well-organised, and conceptually grounded. Reviewers on GMAT Club call the videos "clear, concise" and "easy to consume," and students specifically credit the instruction with teaching strategic shortcuts they would not have found alone ("their lessons were phenomenal and they greatly helped me figure out strategic shortcuts"). The format is voiceover-over-slides with no instructor on screen, which several reviewers find effective but visually flat compared to Manhattan Prep or TTP. The Verbal teaching draws the most criticism: GMATking94 said the "Verbal course seems very old and needs refurbishment," a recurring theme that pulls the instructor score below the Quant-only ceiling it would otherwise reach.

Value is Magoosh's single strongest dimension and the near-universal reason reviewers recommend it. Premium GMAT access runs roughly $199 for 6 months or $249 for 12 months — about one-third the price of Kaplan (~$1,000) and Princeton Review (~$800), and a fraction of premium platforms like TTP or e-GMAT. Payment plans start around $54. GMAT Club reviewers repeatedly use the exact phrase "bang for buck," and Test Prep Insight rated the course 9.1/10 calling it "the best bang for your buck in GMAT prep." A 12-month access window, a 4.5-rated mobile app, a free 7-day trial (30+ lessons, 30 questions), and a tiered score guarantee all reinforce that a low price does not signal a thin product. For budget-conscious or first-attempt test-takers, the value case is hard to beat.

The course includes 1,300+ practice questions, each paired with both a text and a video explanation — a genuinely distinctive feature, since most prep companies do not film an explanation for every single problem. A custom practice tool lets students build targeted quizzes by topic and difficulty. The limitations are real and frequently cited. There are only 2 full-length practice tests, and they are generated from the same question pool as the drills, so heavy users hit repeated questions (reviewer whatsarc flagged "repetitive practice questions"). Several students wanted "more questions in quant," more Data Insights items, and additional mocks. Some also found the Verbal questions diverge from real GMAT difficulty (BelronMajes: "Verbal questions differ significantly from actual test"). It is enough to learn on, but most reviewers pair it with the Official Guide and free official mocks.

Magoosh's own review page documents seven student entries with gains of +100 to +250 points, landing final scores of 700–730, with quotes like "over the last few months, Magoosh improved my score from 490 to 710." The company advertises an average improvement of roughly 90 points and backs a tiered guarantee: up to a 70-point increase for baseline scores below 630, 50 points for 640–690, and 10 points for 700+, or your money back. GMAT Club reviewers report concrete gains of +40 to +140 points and final scores from the high-500s (Focus scale) up to 760 (11Karan, +50). The caveat is honest: the strongest gains cluster around Quant, and a minority flagged the in-product score predictor as inaccurate, so the headline averages should be read as outcomes for committed self-studiers, not guarantees for everyone.
