GRE Complete Prep: How to Score 330+ for Top Grad Schools vs CompTIA Security+ (SY0-701) Complete Course & Practice Exam

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.

The course covers all five SY0-701 exam domains across 264 modules and 31 hours of video, spanning General Security Concepts, Threats and Vulnerabilities, Security Architecture, Security Operations, and Security Program Management. Reviewers on OpenCourser and Reddemy consistently praise the structured domain breakdown, acronym walkthroughs, and the alignment with official CompTIA exam objectives. The main content gap flagged by multiple learners is limited hands-on lab simulation — the course is predominantly lecture-based, which can make performance-based question (PBQ) preparation less thorough than the actual exam requires.

Jason Dion brings over 20 years of IT and cybersecurity experience to the course and is consistently described by reviewers as easy to follow, thorough, and amiable. OpenCourser reviewers Victor Cabrales and Mark Guillen both called out his clear explanations and acronym-focused teaching style as the course's standout feature. He holds CompTIA Platinum Partner status, and Dion Training's 4.6+ star network-wide rating across 2 million+ students reinforces his reputation as one of the most reliable certification prep instructors in the field.

The course is almost always available on Udemy for $13–$20 during the platform's frequent sales, a price point that Reddemy commenters repeatedly highlight as exceptional for 31 hours of content plus practice materials. One Reddemy user noted purchasing both the course and the separate practice exam set for approximately $13 each during a sale. At that price, Dion's course delivers one of the lowest cost-per-hour ratios of any paid Security+ preparation resource, with lifetime access and periodic content updates included.

Multiple reviewers who passed SY0-701 on their first attempt credit Dion's course as their primary preparation resource, including John T. (Medium), who passed in under two months with no prior cybersecurity background. The course's exam-focused framing maps tightly to Security+'s five domains and the career skills they represent — threat analysis, security architecture, and incident response. However, the lecture-only format and absence of hands-on labs mean learners entering cybersecurity roles will need additional practical experience beyond what the course alone provides.

Like most Udemy courses, learner support is limited to the platform's Q&A section — there is no live instructor interaction or direct email support. One Reddemy user flagged a structural navigation issue, noting difficulty jumping directly to specific domains without watching the course sequentially. Response times in the Q&A section are generally adequate for a high-enrollment course, but learners who need real-time feedback or personalized guidance will need to seek supplementary communities such as the r/CompTIA subreddit.
