TOEFL iBT (26+) Complete Preparation Course vs Magoosh GMAT Prep
Same Bayesian formula, same rubric — so the difference in scores reflects the difference in the courses, not the difference in how we evaluated them.

Magoosh GMAT Prep
Per-criterion
A genuinely deep, well-structured library — roughly 50-53 hours of video across Reading, Listening, Speaking and Writing, with 87 downloadable resources, section-by-section strategy breakdowns, and content kept current with the redesigned TOEFL iBT (the Academic Discussion writing task). Reviewers consistently call it "probably the most in-depth course you'll find." The main content caveat is that it assumes intermediate-plus English and is not a beginner English course.
Keino Campbell is the single strongest asset in the package — a Udemy Top 10% Most Engaging Instructor, CELTA-certified ESL specialist, university professor and attorney, with 35,000+ five-star reviews across his TOEFL and IELTS catalogue. Clarity, examiner-awareness and the rare free monthly live group classes draw near-universal praise.
List price around $60-85 but very frequently on sale, with lifetime access, monthly live classes, a certificate and Udemy's 30-day refund. That is a fraction of Magoosh, Kaplan or a tutor. The honest catch is that it leans on standard ETS/official practice rather than bundling its own full-length proprietary mock tests, so serious test-takers buy official material on top.
Strong at the technique level — 30+ assignments, quizzes, and timed Reading/Listening practice that simulates exam pressure — but the most-repeated criticism is that there are no full-length proprietary mock tests created specifically for the course, and the dedicated speaking- practice library is thinner than learners want. Most reviewers recommend pairing it with official ETS TOEFL practice.
Self-reported gains are common and specific across reviews — overall scores up 10-20 points, Reading reaching the 26-27 target band. Because the strategies map onto how the TOEFL is actually scored, motivated self-studiers who do the timed practice tend to report real movement, though reviewers stress success still requires consistent effort.
Magoosh GMAT Prep covers all three GMAT Focus Edition sections — Quantitative, Verbal, and Data Insights — across 340+ short on-demand video lessons, and the curriculum was rebuilt after the Focus Edition replaced the classic GMAT on February 1, 2024. The Quant content is the standout: GMAT Club reviewers (Aabhash777, BelronMajes, GMATking94) repeatedly praise it for teaching from the basics and deriving formulas "from root level" rather than asking students to memorise. The consistent content weakness is Verbal, which multiple reviewers call "old," in need of "refurbishment," and structurally confusing with no continuity. Data Insights coverage exists but several students wanted more practice volume there given how central DI now is to the Focus Edition. The slideshow-with-voiceover format is instructionally sound but, as Test Prep Insight notes, "lacks production value."
The lessons are anchored by long-time Magoosh GMAT expert Mike McGarry, whose Quant explanations are described as crisp, well-organised, and conceptually grounded. Reviewers on GMAT Club call the videos "clear, concise" and "easy to consume," and students specifically credit the instruction with teaching strategic shortcuts they would not have found alone ("their lessons were phenomenal and they greatly helped me figure out strategic shortcuts"). The format is voiceover-over-slides with no instructor on screen, which several reviewers find effective but visually flat compared to Manhattan Prep or TTP. The Verbal teaching draws the most criticism: GMATking94 said the "Verbal course seems very old and needs refurbishment," a recurring theme that pulls the instructor score below the Quant-only ceiling it would otherwise reach.
Value is Magoosh's single strongest dimension and the near-universal reason reviewers recommend it. Premium GMAT access runs roughly $199 for 6 months or $249 for 12 months — about one-third the price of Kaplan (~$1,000) and Princeton Review (~$800), and a fraction of premium platforms like TTP or e-GMAT. Payment plans start around $54. GMAT Club reviewers repeatedly use the exact phrase "bang for buck," and Test Prep Insight rated the course 9.1/10 calling it "the best bang for your buck in GMAT prep." A 12-month access window, a 4.5-rated mobile app, a free 7-day trial (30+ lessons, 30 questions), and a tiered score guarantee all reinforce that a low price does not signal a thin product. For budget-conscious or first-attempt test-takers, the value case is hard to beat.
The course includes 1,300+ practice questions, each paired with both a text and a video explanation — a genuinely distinctive feature, since most prep companies do not film an explanation for every single problem. A custom practice tool lets students build targeted quizzes by topic and difficulty. The limitations are real and frequently cited. There are only 2 full-length practice tests, and they are generated from the same question pool as the drills, so heavy users hit repeated questions (reviewer whatsarc flagged "repetitive practice questions"). Several students wanted "more questions in quant," more Data Insights items, and additional mocks. Some also found the Verbal questions diverge from real GMAT difficulty (BelronMajes: "Verbal questions differ significantly from actual test"). It is enough to learn on, but most reviewers pair it with the Official Guide and free official mocks.
Magoosh's own review page documents seven student entries with gains of +100 to +250 points, landing final scores of 700–730, with quotes like "over the last few months, Magoosh improved my score from 490 to 710." The company advertises an average improvement of roughly 90 points and backs a tiered guarantee: up to a 70-point increase for baseline scores below 630, 50 points for 640–690, and 10 points for 700+, or your money back. GMAT Club reviewers report concrete gains of +40 to +140 points and final scores from the high-500s (Focus scale) up to 760 (11Karan, +50). The caveat is honest: the strongest gains cluster around Quant, and a minority flagged the in-product score predictor as inaccurate, so the headline averages should be read as outcomes for committed self-studiers, not guarantees for everyone.
