CompTIA Security+ (SY0-701) Complete Course & Practice Exam vs Magoosh GRE Prep

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.

Magoosh provides 290+ video lessons covering Quantitative, Verbal, and Analytical Writing, plus 1,600+ practice questions — 160 of which are licensed official ETS problems, making Magoosh the only US GRE prep company with access to these materials. Independent reviewers at Test Prep Insight confirm the practice problems are "a close match for the real GRE" and that it would be "hard to decipher real GRE problems from most of Magoosh's mock problems." The main content criticism is that hard-level Magoosh quant questions can exceed actual GRE difficulty, and the curriculum occasionally presents problems before the relevant concepts have been fully taught in the video lessons.

Tutors Chris Lele and Mike McGarry — the primary Magoosh GRE instructors — are recognized as experienced GRE educators who know their material deeply and present it clearly. GRE tutor Vince Kotchian (15+ years experience) specifically called them out as experienced teachers with strong instructional abilities. The consistent criticism is the delivery format: PowerPoint-style slides with voiceover rather than an instructor on camera, which multiple reviewers describe as "not the most engaging" and less polished than Kaplan's dynamic whiteboard format.

At $149 for one month or $179 for six months, Magoosh is consistently described as an "absolute steal" and "bang for the buck" by independent reviewers — especially compared to Kaplan ($599), Manhattan Prep ($599+), and Princeton Review ($449+). The +5 point score guarantee with a full refund option (verified by actual users who received refunds) and a 7-day no-questions-asked return window add additional low-risk appeal. Test Prep Insight calls the pricing "an absolute steal," and EduReviewer assigns value-for-money a 4.5/5 score. The Live Classes add-on at $499 is seen as significantly less attractive value.

Magoosh provides 24/7 email support from GRE tutors, with response times reported consistently within 24 hours and often faster. Top Consumer Reviews (June 2026) notes customers report "getting feedback on their questions super fast and the responses are super helpful." The platform also includes in-app contextual help, score predictor tools, and links from each question to relevant lesson videos. The limitation is the absence of live chat or phone support — communication is email-only — and no private tutoring is bundled in the standard plan. Live class sessions (extra cost) add real-time interaction but are excluded from the core subscription.

Magoosh reports an average student score increase of 5–6 points and a 5-point improvement guarantee. Verified reviews on gre.magoosh.com show students reaching scores of 322–335, with one student improving from 310 (157Q/153V) to 324 (165Q/159V). EduReviewer notes that 20% of Magoosh users score in the top 10%. GRE tutor Vince Kotchian's honest caveat is that Magoosh "is best for students in the middle who want structure and are okay with a score below 320" — those targeting 165+ per section may find the question difficulty ceiling insufficient for their goals, particularly on the quantitative side.
