Master Microsoft Azure Fundamentals: AZ-900 Exam Prep vs Magoosh GMAT Prep

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.

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.
