Duolingo English Test: Write About The Topic
The course is praised for clear, structured explanations of the Write About the Topic task type — covering what the prompt expects, how the scoring rubric works, timing strategies, and common mistakes. Reviewers from the DET preparation community consistently describe the instruction as practical and actionable rather than generic. However, the content is scoped to a single question type in a test that has multiple distinct task formats, and it was last updated in February 2021. The 2024 Duolingo English Test format update introduced Interactive Writing and revised Fill in the Blanks mechanics; those changes are not reflected in this course. For learners focused purely on written production within the pre-2024 DET format, the content quality is high. For a learner preparing holistically for the current test, it covers only one slice of what they need.
Luke Jones carries a verified 4.6/5 instructor rating on Udemy across 22,763 students and 4,613 total ratings spanning his three courses. Learners across multiple sources describe his instructional style as clear, methodical, and easy to follow — he explains the rationale behind every strategy rather than just listing tips. His DET preparation community has helped hundreds of learners, and score-improvement stories tied to his advice (120 overall on a first attempt, scores of 130 and 140 after following his guidance) appear across multiple independent blogs. The instructor is the strongest single asset of this course, and the consistently high aggregate rating across a large student base is a reliable signal of teaching quality.
At Udemy's standard sale pricing (typically $10-15), a 2.5-hour course focused on one DET task type is a reasonable supplementary purchase for a learner who already has a broader study plan. The honest concern is that the course is narrow in scope, has not been updated since 2021, and does not cover the full DET. Learners expecting a complete preparation package at this price are likely to feel shortchanged. As a targeted supplement — bought specifically to sharpen performance on written production tasks — the value-for-money calculus is much more favourable. The 30-day Udemy money-back guarantee provides a safety net, but the gap between the course's actual scope and what many DET learners are searching for is a real value-perception risk.
The course includes model responses and worked examples for Write About the Topic prompts, which reviewers find helpful for understanding the standard to aim for. However, the practice-question bank is limited within a 2.5-hour course, and there are no adaptive mock-test environments, no full DET simulations, and no AI-generated feedback on learner responses. Dedicated DET practice platforms such as DET Ready (detready.com) offer 750,000+ users and AI-scored practice at a different scale. For raw practice volume, this course cannot compete with purpose-built DET drill tools; its value is in the strategy instruction that sits alongside any practice resource, not in providing that practice itself.
Score-improvement outcomes tied to Luke Jones's instruction are consistently positive across sources: learners report achieving 120, 130, and 140 overall DET scores after applying his strategies. One learner specifically attributes a production subscore improvement from 75 to 100 to targeted instruction. A learner passed on their first attempt with 120. These outcomes are credible given the instructor's large following and high aggregate satisfaction. The caveat is that the testimonials cannot be attributed exclusively to this Udemy course versus Jones's YouTube channel, website resources, or other course material — his DET content spans multiple formats. Learners seeking a guaranteed score lift should treat this course as one component of a multi-resource study plan rather than a standalone preparation solution.
TOEFL iBT (26+) Complete Preparation Course
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.
