AZ-104 Microsoft Azure Administrator — Complete Exam 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.
Comprehensive GMAT Prep: Self-Study Guide to GMAT 700+
The course is positioned as a consolidated self-study strategy guide rather than a full content syllabus: it teaches how to plan a GMAT preparation, how to attempt questions, and how to track progress, rather than re-teaching every quant and verbal concept from scratch. Reviewers describe it as covering "all important aspects of the GMAT exam in an easy to comprehend manner," and the standout asset is a specially designed MS-Excel GMAT Analysis Tool plus consolidated revision notes. The honest limit is breadth — it is a strategy and planning layer, not a comprehensive concept course, so a true beginner will need separate material to actually learn the maths and grammar.
The instructor's credibility rests on a concrete, verifiable claim: a GMAT 740 (Q50, V40) on the first attempt achieved through self-study. That is a strong, top-percentile result and it gives the strategy advice real weight, because the whole course is essentially "here is exactly what I did." The teaching philosophy — "if I was able to crack the GMAT through self-study, anyone can" — is encouraging and the test-day strategy insights are the part learners single out as genuinely useful. The deduction is transparency: the instructor's full name and broader teaching track record are not prominently published, so you are trusting one person's score story rather than an established prep brand.
This is the course's strongest dimension. It is explicitly priced "at the lowest possible price" and is regularly available very cheaply or via free coupons, with lifetime access and Udemy's 30-day refund. For the cost of a single coffee you get a structured self-study roadmap, an Excel tracking tool and revision notes from a 740 scorer — a tiny fraction of what Target Test Prep, Manhattan Prep or e-GMAT charge. The fair caveat is that the low price reflects scope: you are buying a plan and tools, not thousands of practice questions, so the real cost of your prep is this plus the official GMAT material you still need to buy.
The weakest area and the one most likely to disappoint buyers who expect a question bank. The course includes some solved questions to illustrate the attempting strategy, but it is not a high-volume practice resource — there are no full-length adaptive mocks and no large bank of original problems. Its own design assumes you will do your heavy practice in the Official Guide and GMAT Official Practice Exams; the course's job is to tell you how to use them efficiently and track your weak areas with the Excel tool, not to be your practice source.
The realistic value proposition is structure and efficiency rather than a guaranteed point jump. Learners credit the test-day strategy and the self-analysis tool with helping them prepare smarter, and the 740-scorer framing maps the plan onto a genuinely high outcome. But because the course supplies little practice and no full mocks, any score gain depends almost entirely on the learner pairing it with official material and doing the timed reps — the course is the map, not the miles.
