Per-criterion

Content quality4.3 / 5

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.

Instructor4.4 / 5

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.

Value for money4.0 / 5

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.

Practice material2.8 / 5

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.

Score improvement3.9 / 5

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.

Content quality3.7 / 5

The course covers Sentence Correction (the "Big 6" grammar rules), Critical Reasoning, and Reading Comprehension across six-plus hours of instructional video. Learners consistently praise the clarity and structure — one student called the material "simple, straightforward and digestible" and credited Brett's "strategies and approaches for thinking quicker." However, the GMAT Focus Edition launched November 7, 2023 and completely removed Sentence Correction from the test, which was one-third of the classic verbal section. A course that still dedicates substantial runtime to a question type that no longer earns test-takers any points carries a content-currency problem that is structural, not stylistic.

Instructor4.2 / 5

Brett Ethridge is the course's strongest asset. A Duke University graduate and MA holder in International Finance, he has an instructor rating of 4.4 on Udemy across 3,199 reviews and is consistently praised for making complex verbal reasoning intuitive. Students describe him as having "fantastic teaching and amazing subject knowledge" and say the course "gave me tools to be confident with the test." Multiple students report 100–150 point score improvements they credit directly to his methods, and one debrief on GMAT Club singles him out by name: "The thing I enjoyed most about his style of teaching was that it was simple, straightforward and digestible."

Value for money3.8 / 5

At typical Udemy sale pricing (under $20 with lifetime access), Dominate GMAT Verbal is dramatically cheaper than the $147 standalone verbal plan on Brett's own DominateTestPrep.com or any full-platform competitor. Learners from the GMAT Club forum bought both this and a second Udemy verbal course for under $10 combined during a Black Friday sale, with one poster summarising the calculus as "Try it — it's virtually free." The honest offset is the GMAT Focus content problem: you are paying, however little, for a course that devotes significant time to Sentence Correction, a skill the current GMAT no longer tests.

Practice material3.0 / 5

The course includes worksheets for each of the six Sentence Correction grammar categories and reading comprehension and critical reasoning drills — adequate for reinforcement but not a high-volume question bank. Serious GMAT Club users consistently note that GMAC official practice tests are the only questions that truly mirror the adaptive exam, and neither this course nor any Udemy GMAT offering includes official GMAC material. For realistic GMAT Focus practice, learners must separately purchase the official GMAT prep software and question packs, making this course a teaching layer rather than a primary practice engine.

Score improvement3.9 / 5

Where the course still lands well is on transferable reasoning skills. Critical Reasoning and Reading Comprehension — the two verbal question types retained in GMAT Focus — are taught rigorously, and multiple students report that Brett's structured approach to dissecting RC passages and CR arguments carried them on exam day. Student Georges Kazan (Quebec) specifically called out "Critical Reasoning tools were incredibly helpful," and another student described the experience as "like being handed a flashlight and a map" for an exam that had previously felt overwhelming. These skills also transfer directly to the verbal sections of the LSAT and GRE.
