Duolingo English Test: Write About The Topic vs Magoosh ACT 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.

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.
Magoosh ACT Prep
Magoosh ACT Prep covers all four ACT sections — English, Math, Reading, and Science — across 250+ video lessons, with optional Writing content available. The course has been updated for the Enhanced ACT format, and reviewers at EduReviewer and Sojourning Scholar confirm that the content accurately reflects current exam structure and difficulty. Lead instructor Erika holds 99th-percentile scores on the ACT, SAT, GRE, and GMAT, lending strong credibility to the instruction. A critical note from the PrepScholar comparison blog is that some video lessons were found to contain errors in ACT scoring system information, which slightly offsets the otherwise strong content quality score.
The teaching team at Magoosh is consistently described as "personable and clear" by Test Prep Insight reviewers, and students specifically cite strategy-first instruction that goes beyond memorisation — teaching how to "find the main idea quickly and beat the clock" and providing "tips and tricks to improve overall score." Lead tutor Erika's 99th-percentile credentials are prominently featured. The main criticism is the whiteboard-style video format, which multiple reviewers describe as slightly "on the boring side" despite being instructionally sound. The PrepScholar comparison also flagged specific lesson errors in earlier versions of the course, which Magoosh has since addressed in updated modules.
Magoosh ACT Prep is widely regarded as the best-value ACT prep option in the industry. At $99–$129 for 12-month access — or as little as $79 for a one-month plan — it costs roughly one-tenth of traditional private tutoring ($1,000+) and significantly less than Kaplan ($449–$1,000+) or Princeton Review ($799–$1,599). The 82,000+ students served and a backed +4 point score improvement guarantee (or full refund) are strong signals of institutional confidence in the product. Both Test Prep Insight (9.0/10) and EduReviewer (4.6/5) cite value as Magoosh's single strongest dimension.
The course includes 1,500+ practice questions and four full-length ACT practice tests, each with detailed video and text explanations for every question — a distinctive feature not found in all competitors. Customisable practice drills allow targeted section work. The main limitation, flagged by both Test Prep Insight and the PrepScholar comparison blog, is that the four practice tests are generated from the same question bank rather than being fully unique exams, creating potential overlap if a student cycles through all four. Princeton Review offers 11 simulated ACTs to Magoosh's four, making Magoosh thinner on full-test volume for students who need repeated full-exam simulation.
Magoosh's own review page documents seventeen score improvement entries from students who reached final scores of 28–34, with individual improvements ranging from +1 to +12 composite points. The most commonly reported gains are +3 to +5 points. One student improved from 28 to 33 using Magoosh exclusively. The company reports helping more than 82,000 students, and their score improvement data page (Magoosh Schools Blog) shows that users outperform national averages when they commit 30–40 hours of preparation. The guaranteed +4-point improvement for students scoring under 30 is a meaningful benchmark backed by a refund policy.
