Tutors sell a practice test review by having the student send their completed exam and score report, then returning a written or recorded breakdown of missed questions, the patterns behind them, and what to study next. On Brillay this is a priced custom request with a set turnaround, so feedback happens once, asynchronously, without a booking call. Custom Work lets you offer clearly scoped commissions and services: you set the price, the scope and the delivery time, and followers submit a brief and pay before you start.
No monthly fee, you only pay a small platform fee when you get paid. 8% platform fee when a follower pays for work, 5% platform fee on tips and goals. Card processing is separate. pricing
A practice test only helps if someone reviews what went wrong. College Board's guidance for its Bluebook practice tests tells students to "keep track of the questions you missed and pay attention to any patterns you notice about the question content and the skills involved" (SAT Suite: How to Use Bluebook Practice Tests). That instruction hands the diagnosis to the student. A paid review is a tutor doing the diagnosis instead: reading the same missed questions and naming the pattern out loud.
"Keep track of the questions you missed and pay attention to any patterns you notice about the question content and the skills involved." — College Board, How to Use Bluebook Practice Tests
A practice test review is a different offer from live tutoring. A booked session works in real time, question by question. A practice test review works after the fact, on a document the student already has: a completed exam, a PDF score report, or a screenshot of results. There is no call to schedule.
What counts as a practice test review?
A practice test review is feedback on a student's own completed exam attempt — not a new set of questions, and not a forward-looking study plan. The student sends the finished test (or its score report) and the tutor returns an analysis of what they missed and why, plus specific next steps before the next attempt.
The deliverable typically covers three things: which questions were missed, what those misses have in common (a section, a question type, a recurring careless error), and what to focus on before the next sitting. A practice test review is not the same product as writing new practice content, and not the same product as building an ongoing prep schedule — both of those are separate offers on their own, the same way a structured weekly practice plan for a music student is a distinct deliverable from a one-time review.
Scale is why scope has to be written down. One full-length digital SAT contains 98 questions and 134 minutes of testing — 64 minutes for Reading and Writing plus 70 minutes for Math (College Board: SAT Suite Test Structure). Reviewing all 98 items is a materially bigger job than explaining one.
Because a review works from a document the follower already has, the offer fits Custom Work: the follower attaches the completed test or score report as one of up to 5 files when ordering, and the tutor delivers a written note plus files — video, audio, images, PDF, Word, Excel, or PowerPoint, with delivered video or audio capped at 20 minutes — or a private link for anything larger.
Should you scope this as a full review or a single question?
Scope by how much of the test needs attention and whether a document has to change hands. A single missed item fits Paid Questions: one typed question and one written reply. A full section or a full-length exam requires the student to send a test or score report, so Custom Work is the better fit.
Test length is why the split matters. The core ACT runs 131 questions across three sections — English (50 questions, 35 minutes), mathematics (45 questions, 50 minutes), and reading (36 questions, 40 minutes) — plus an optional 40-question, 40-minute science section (ACT: Exam Sections and Structure). Explaining one of those 131 items is a message; explaining all of them is a project.
Paid Questions are one typed question and one written reply. Custom Work accepts attached files from the follower, and the creator can deliver files, audio, or video (how it works).
| Request | Better-fit offer | Why |
|---|---|---|
| One missed question, explained | Paid Questions | One written reply |
| Full section or full-length test reviewed | custom request | Requires a file or score-report upload |
| Recorded walkthrough of the whole exam | custom request | Audio/video delivery needs full-media support |
| Forward-looking study plan, not tied to one test | A separate study-plan service | Different deliverable — a plan, not a review |

What should the review actually include?
A useful practice test review names the score, the missed items, the pattern behind them, and a next step — not just a list of right and wrong answers. Students can already see which answers were wrong from their own score report; what they are paying for is the interpretation of those wrong answers.
A minimal but complete structure looks like:
- Score context: the section or subscore, and how it compares to the student's stated target.
- Missed-item breakdown: which questions were missed, grouped by type (careless error, timing, concept gap, guessing).
- Pattern callout: the one or two recurring issues driving most of the missed points — a raw score report cannot surface a recurring issue on its own.
- Next-step focus: two or three concrete things to practice before the next attempt, not a full new curriculum.
Feedback research is specific about why the explanation is the valuable part. Fazio, Huelser, Johnson and Marsh found that subjects who received right/wrong feedback performed no better than subjects who received no feedback at all on overall retention of correct answers in Experiments 1 and 2 (Fazio et al., "Receiving right/wrong feedback: consequences for learning", Memory 18(3), 335–350, 2010). The same 2010 paper reported one narrow exception: for low-confidence correct answers, right/wrong feedback was as effective as full correct-answer feedback.
Explanation goes further than the correct answer alone. Butler, Godbole and Marsh found that explanation feedback and correct-answer feedback produced equivalent performance on repeated questions, but explanation feedback produced better performance on new inference questions that tested transfer (Butler, Godbole & Marsh, "Explanation Feedback Is Better Than Correct Answer Feedback for Promoting Transfer of Learning", Journal of Educational Psychology 105(2), 290–298, 2013). A review that explains why an answer was wrong is delivering the feedback type that 2013 study associated with transfer.
Why is reviewing a missed test worth paying for?
The learning-science evidence supports the testing, not the review fee — so state the claim carefully. Dunlosky and colleagues evaluated 10 common study techniques and rated exactly two of them high utility: practice testing and distributed practice. Taking a practice test is free. What a student pays a tutor for is the interpretation of the misses.
Dunlosky, Rawson, Marsh, Nathan and Willingham reviewed 10 learning techniques and concluded that "practice testing and distributed practice received high utility assessments," while widely used techniques including highlighting, summarization, and rereading were rated low utility (Psychological Science in the Public Interest, 14(1), 4–58, 2013, abstract).
"Practice testing and distributed practice received high utility assessments." — Dunlosky, Rawson, Marsh, Nathan & Willingham, Psychological Science in the Public Interest, 14(1), 2013
That 2013 finding is about self-testing and spacing, not about paid review, and it should not be stretched into one. No study cited on this page measures the effect of a tutor's paid written review of a missed practice test. The defensible version is narrower: practice testing is strongly supported, explanation feedback beats correctness-only feedback on transfer questions, and a paid review is one delivery mechanism for that explanation feedback.
How much does a real test attempt cost — and why that matters for pricing
Anchor a review's price against the cost of sitting the real exam again. The SAT registration fee is $68, the ACT costs $70 plus an optional $5 science add-on, and the GRE General Test costs $249 in the United States. A review priced well under a retake is easy to justify to a skeptical student.
College Board lists the SAT registration fee at $68 (SAT Suite: Test Fees). ACT, Inc. lists the ACT (EMR composite, covering English, math, and reading) at $70.00, with the science section as a $5.00 add-on (ACT: Registration Fees). ETS lists the GRE General Test registration fee in the United States at $249, effective August 1, 2026 (ETS: GRE General Test Fees). Those anchors do not apply to every student: College Board's fee-waiver program lets eligible low-income 11th- and 12th-grade students in the US take two SAT tests for free (SAT Fee Waivers), so a retake-cost argument lands differently with a fee-waiver student.
| Reference cost | Amount | Source |
|---|---|---|
| SAT registration fee | $68 | College Board |
| ACT test (EMR composite) | $70 | ACT, Inc. |
| ACT science add-on | $5 | ACT, Inc. |
| GRE General Test (US) | $249 | ETS |
Example price tiers for an async review
The tiers below are illustrative structures for scoping an offer, not Brillay prices, averages, or earnings claims. Actual pricing depends on subject, audience, demand, and how the offer is positioned.
| Tier | What the student sends | What they get back | Illustrative price |
|---|---|---|---|
| Single missed question | The question and their answer, typed | A written explanation | $10–$20 |
| Section review | One section or module plus its score report | Missed-item breakdown and one named pattern | $25–$50 |
| Full-test review | One completed full-length test plus score report | Full breakdown, pattern callout, two focus areas | $50–$90 |
| Recorded walkthrough | One completed full-length test plus score report | A recorded video walkthrough plus a short written summary | $80–$150 |
Fee math is easy to state exactly. On an illustrative $60 full-test review, Brillay's 8% platform fee is $4.80, leaving $55.20 before payment processing; tips and goals carry a 5% platform fee instead. Stripe's published typical US online-card rate of 2.9% + $0.30 works out to $2.04 on that same $60 charge (Stripe: Pricing); international cards, currency conversion, and manually entered cards carry additional Stripe fees.
How do you write the listing so requests stay in scope?
A clear listing states what document is required, what the deliverable covers, and what is excluded, so a follower knows exactly what they are paying for before submitting anything. Vague listings like "I'll review your test" invite oversized requests: three practice tests instead of one, or a full new study plan bundled in free.
A tighter version might read: "Send one completed practice test (PDF or clear photos) plus your score report. You'll get a written breakdown of missed questions, the pattern behind them, and two focus areas for your next attempt. Does not include new practice questions or a full study schedule." A submission that goes beyond that scope — a second test, a different subject entirely — can be declined rather than absorbed as extra work.
For Custom Work, you set the delivery window from one to five days. A 24- or 48-hour window matters more for test review than for most services, because students are usually working against a fixed retake date. Missing that date is expensive: College Board charges $38 for late SAT registration and $34 to change a test center on top of the $68 base fee (SAT Suite: Test Fees).
What else fits alongside a practice test review?
A practice test review does not have to be a tutor's only paid offer, and requests that fall outside a full review still need somewhere to land. A single explained question, an encouragement video before a retake, a tip, and funding toward a free question bank are four separate formats on one page — and for tutors who also work with college applicants, reviewing a personal statement is another async, document-based offer that fits the same pattern.
- Paid Questions: a single missed question, explained in one written reply.
- Personalized Videos: encouragement before a retake, or a congratulations message after a score improves.
- Tips: a one-time thank-you from a supporter, with nothing to deliver in return.
- Goals: one named funding target, such as a free practice-question bank, with a progress bar and no all-or-nothing cutoff.

Frequently asked questions
What document does a student need to send?
The completed practice test itself (a scanned copy or clear photos) or, at minimum, the official score report showing which questions were missed. Without one of those documents, a tutor cannot identify the actual pattern behind the missed points. Custom Work accepts attached files from the follower at checkout, so the file arrives with the order rather than in a separate message.
Should this be a Paid Question or a custom request?
Use Paid Questions for one specific missed item: one typed question and one written reply. Use Custom Work when the student needs to send a document — a full test, a score report, or a section — because Custom Work accepts attached files from the follower.
How fast does the review have to be delivered?
The creator sets the delivery time, and Brillay's Custom Work delivery window is up to 5 days, a product limit rather than a recommendation. Setting a window well under that cap is the safer choice for test review, because a student ordering one is usually days away from a scheduled retake.
Does a review guarantee a higher score on the next attempt?
No. A review can identify missed-question patterns and suggest focus areas, but it cannot guarantee test-day performance, which depends on many factors outside the review itself. Any pricing or outcome language should avoid implying a guaranteed result.
What if the student sends more than one test?
Set a document limit in the listing (for example, one test per purchase) and either offer a bundled tier for multiple tests or decline a submission that goes beyond the stated scope.
What does Brillay charge for this?
Brillay's own platform fee is the rate stated above, separate from payment processing; Stripe's published typical US online-card rate is 2.9% + $0.30 per successful domestic-card transaction (Stripe: Pricing).
