GRE Math Prep Course: The A–Z on GRE Math Topic by Topic vs Magoosh IELTS 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 IELTS Prep
Per-criterion
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.
Magoosh IELTS provides roughly 120+ video lessons covering Listening, Reading, Writing, and Speaking, plus 600+ practice questions (Sojourning Scholar counts closer to 900 once Speaking and Writing prompts are included). Lessons are short, mostly under 15 minutes, with closed captions and full transcripts on every video — a feature multiple reviewers single out as valuable for non-native speakers. EduReviewer calls the course "an excellent comprehensive course for everyone who looks forward to passing this test," and englishproficiency.com rates the platform 4.5/5 for its high-quality study material. The recurring criticism is that the Reading and Listening practice can run harder than the real exam, and that the video format is slide-with-voiceover rather than an on-camera instructor.
Lessons are delivered as slides with voice-over narration from instructors that Sojourning Scholar describes as "very knowledgeable about IELTS test-taking strategies." All Language Resources notes that while the video lessons "might not make it the most exciting resource, the serious learner will get plenty of quality test prep." Recent plan updates added live drop-in classes with an IELTS expert, which reviewers at EduReviewer flagged as a genuine edge over purely self-paced competitors. The consistent limitation is engagement: the PowerPoint-style delivery is functional rather than dynamic, and live instruction is limited to drop-in sessions rather than a structured live course.
At roughly $99–$129 for six months (with a 1-month option around $109 and installment plans of about $32/month), Magoosh IELTS is consistently described as one of the best values on the market. E-Student concludes Magoosh delivers "great value for money and a high degree of personalization," and ieltsit.com calls it "one of the popular budget options" and "one of the best values available." Brighterly and EduReviewer both rate value highly relative to Kaplan, Princeton Review, and PrepScholar. The 7-day no-card-required free trial and full money-back guarantee further lower the risk, though some Trustpilot users report disputes over refund eligibility.
Magoosh provides up to 10 full-length mock tests (more than Kaplan's four, per multiple reviews), 600+ practice questions, graded Speaking and Writing assessments, and an unlimited Ask-an-Expert email feature praised by Sojourning Scholar for its "detailed responses" from instructors within 24 hours. The Listening section is repeatedly called close to real test difficulty. The limitations: the Reading questions are widely reported as harder and trickier than the actual IELTS, and the Speaking assessment historically lacked an audio-upload review path, so spoken feedback is more limited than written feedback.
Magoosh offers a 0.5-band score-improvement guarantee with a full refund if you do not improve, and reviewers note the platform is "very helpful in raising students' test scores." The guarantee carries strict conditions: you must set a target score, watch all lesson videos, sit at least two mock tests, complete the full practice question bank, use all Speaking and Writing assessment credits, follow a study schedule, and contact a Magoosh expert. The dashboard band-score predictor becomes more accurate as you answer more questions, helping learners judge readiness. The honest caveat is that improvement depends heavily on the learner's self-discipline, since the course is entirely self-guided.
