GRE Math Prep Course: The A–Z on GRE Math Topic by Topic vs TOEFL iBT (26+) Complete Preparation Course

The course is a tightly-organised library of 240 worked GRE quant solutions across ~13 hours, taught topic by topic from the absolute basics up through harder material like probability. Reviewers consistently praise the clear, step-by-step breakdowns and the memorable mnemonic devices (the "Beyonce Rule" is the one people quote back). The recurring content caveat is that it is purely solution walkthroughs — there are no embedded original practice questions, so the "content" is teaching, not testing.

Olu Sanya is the strongest part of the package. A Morehouse/Georgia Tech Applied Physics and Electrical Engineering graduate with 14+ years of test-prep experience, he is repeatedly described as engaging, patient and good at making a nervous student feel math is learnable. His stated philosophy — "it's not difficult, you just don't know it yet" — shows up in the teaching, and the free 1-hour Skype session he offers is a rare personal touch at this price.

List price is around $70 but the course is almost always on sale in the $10-20 band with lifetime access, plus a free formula-sheet PDF and a bonus Skype session — genuinely cheap versus Magoosh, Manhattan or Target Test Prep. The honest deduction is that you are required to buy Barron's 6 GRE Practice Tests separately to actually use the videos, so the true out-of-pocket cost is higher than the headline, and independent reviewers note Barron's is not the best-regarded practice source.

The weakest dimension by a wide margin and the one every critical source agrees on. The course contains no independent practice questions, no quizzes and no full-length tests — it is built entirely around explaining problems from an external Barron's book you must purchase yourself. BrightLink Prep is blunt that "there are no practice exercises crucial to forming a solid understanding," and points out Barron's is a questionable choice versus official ETS material.

Learners credit the method with building confidence and giving them concrete strategies for question types they previously froze on, and the topic-by-topic mastery approach maps well onto how GRE quant is structured. But because the course supplies no practice and no full-length mocks, score movement depends entirely on the learner doing the external Barron's (and ideally official ETS) practice on top — the videos teach the how, not the timed reps.

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.
