CompTIA Security+ (SY0-701) Complete Course & Practice Exam vs Magoosh ACT 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 ACT Prep covers all four ACT sections — English, Math, Reading, and Science — across 250+ video lessons, with optional Writing content available. The course has been updated for the Enhanced ACT format, and reviewers at EduReviewer and Sojourning Scholar confirm that the content accurately reflects current exam structure and difficulty. Lead instructor Erika holds 99th-percentile scores on the ACT, SAT, GRE, and GMAT, lending strong credibility to the instruction. A critical note from the PrepScholar comparison blog is that some video lessons were found to contain errors in ACT scoring system information, which slightly offsets the otherwise strong content quality score.

The teaching team at Magoosh is consistently described as "personable and clear" by Test Prep Insight reviewers, and students specifically cite strategy-first instruction that goes beyond memorisation — teaching how to "find the main idea quickly and beat the clock" and providing "tips and tricks to improve overall score." Lead tutor Erika's 99th-percentile credentials are prominently featured. The main criticism is the whiteboard-style video format, which multiple reviewers describe as slightly "on the boring side" despite being instructionally sound. The PrepScholar comparison also flagged specific lesson errors in earlier versions of the course, which Magoosh has since addressed in updated modules.

Magoosh ACT Prep is widely regarded as the best-value ACT prep option in the industry. At $99–$129 for 12-month access — or as little as $79 for a one-month plan — it costs roughly one-tenth of traditional private tutoring ($1,000+) and significantly less than Kaplan ($449–$1,000+) or Princeton Review ($799–$1,599). The 82,000+ students served and a backed +4 point score improvement guarantee (or full refund) are strong signals of institutional confidence in the product. Both Test Prep Insight (9.0/10) and EduReviewer (4.6/5) cite value as Magoosh's single strongest dimension.

The course includes 1,500+ practice questions and four full-length ACT practice tests, each with detailed video and text explanations for every question — a distinctive feature not found in all competitors. Customisable practice drills allow targeted section work. The main limitation, flagged by both Test Prep Insight and the PrepScholar comparison blog, is that the four practice tests are generated from the same question bank rather than being fully unique exams, creating potential overlap if a student cycles through all four. Princeton Review offers 11 simulated ACTs to Magoosh's four, making Magoosh thinner on full-test volume for students who need repeated full-exam simulation.

Magoosh's own review page documents seventeen score improvement entries from students who reached final scores of 28–34, with individual improvements ranging from +1 to +12 composite points. The most commonly reported gains are +3 to +5 points. One student improved from 28 to 33 using Magoosh exclusively. The company reports helping more than 82,000 students, and their score improvement data page (Magoosh Schools Blog) shows that users outperform national averages when they commit 30–40 hours of preparation. The guaranteed +4-point improvement for students scoring under 30 is a meaningful benchmark backed by a refund policy.
