Complete Networking Fundamentals Course: CCNA Start vs GRE Complete Prep: How to Score 330+ for Top Grad Schools

The course spans approximately 79.5 hours of video across all core CCNA 200-301 domains, covering networking fundamentals, OSI and TCP/IP models, IP addressing and subnetting, routing (static routes, OSPF, EIGRP, IPv6), switching, VLANs, Spanning Tree, NAT, ACLs, wireless technologies, QoS, VoIP, and network automation. Reviewers on Reddit and course aggregator sites consistently describe it as "one of the most comprehensive networking courses I have ever seen for the price" and praise its logical, ground-up progression. The course includes GNS3 and Packet Tracer lab demonstrations, cheat sheets, quizzes, and downloadable resources, though a small number of reviewers note it should be supplemented with additional practice exam resources for full 200-301 readiness.

David Bombal holds CCIE #11023 Emeritus, which he earned on his first attempt in January 2003 — a distinction achieved by a very small percentage of Cisco engineers. He has over 20 years of network training experience, has trained engineers at Fortune 100 companies, holds Cisco and HPE certified instructor status, and has over 2 million YouTube subscribers. Reviewers consistently praise his teaching methodology for the care put into scope and learning progression, with one Reddit user describing the course as the result of someone who "invested significant effort into what needs to be learned and in what order." His credentials are regularly cited as a reason students trust the material.

The course is consistently available on Udemy for $11–$20 during the platform's frequent sales, which Reddit reviewers repeatedly highlight as exceptional value. One r/homelab user who purchased it for $13.99 called it "the best purchase I made of thousands I've spent on my homelab over the years." Another r/linuxadmin commenter noted paying "a whopping $11.99" for "one of the most comprehensive networking courses I have ever seen." With nearly 80 hours of content, lifetime access, 18 articles, 124 downloadable resources, and regular updates to keep pace with the CCNA 200-301 exam blueprint, the cost-per-hour ratio is among the lowest of any CCNA prep course on the market.

David Bombal explicitly designs the course for both exam preparation and real-world application — the curriculum covers actual device configuration on simulated Cisco routers and switches via Packet Tracer and GNS3, not just definitions and theory. Reddit discussions in r/homelab, r/linuxadmin, and r/ccna note that the course teaches concepts in a way that applies directly to home labs and enterprise networking jobs, not just to passing an exam. The practical emphasis on configuration, VLANs, routing protocols, and troubleshooting scenarios means graduates are better prepared for entry-level network engineering roles, not just the Cisco certification exam.

The course's integration of GNS3 and Packet Tracer labs throughout the curriculum is the most consistently praised retention element — learners build and configure simulated networks rather than passively watching lectures. Multiple Reddit reviewers credit the hands-on component with making the course worthwhile for both CCNA candidates and general networking enthusiasts. The course length of ~79.5 hours is frequently described as thorough but potentially overwhelming for learners with time constraints, and some reviewers note the instructor's delivery can occasionally be hard to follow during dense technical sections. Overall, the lab-heavy format gives it stronger retention than purely lecture-driven alternatives.

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.
