Four quick taps. We match you with real stories from people who started where you are and hit your target — then turn them into a plan.
Start with the path. Save it when it is useful.
Every debrief, charted. Filter it, tap any bar to open the stories behind it, and read the takeaway under each chart.
Official total score across the filtered set.
Median Q / V / DI score within each target band.
Start-to-official point gain, where a start score was reported.
Each dot is a debrief; the dashed line is the overall trend.
Median total score by weeks of prep.
Median official score by attempt number, where reported.
Share of debriefs naming each — popularity, not proof of effectiveness.
Self-study = only free material (Official Guide, official mocks, GMAT Club…).
Share of each band that mentions a recurring tactic.
Most prep tools start with courses or question banks. PrepSignals starts with your current score, target, timeline, and bottleneck, then uses real GMAT debrief patterns to suggest what to do next.
Build a score path, revisit matching stories, track mock progress, keep a first-week checklist, and use the Study Planner for rule-based next steps.
The dataset summarizes 330 public debriefs from Reddit's r/GMAT and GMAT Club. Every debrief links back to its source so you can inspect the original post.
PrepSignals is not affiliated with GMAC, Reddit, GMAT Club, or any prep company. Resource names come from posters, and promotional-looking debriefs are flagged.
Anonymous paths stay in your browser. Accounts use Supabase to sync your plan, saved debriefs, checklist, progress, and review notes. Marketing email is opt-in.
Colors stay consistent across the app: blue for Quant, purple for Verbal, teal for Data Insights, amber for resources, green for timing, and coral for score gains. Charts describe patterns; they do not promise score outcomes.
Data spans 2023-11-13 to 2026-06-24. Full details: Privacy Policy · Terms of Service.

Welcome to PrepSignals ("PrepSignals", "we", "us"). By using prepsignals.vercel.app (the "Service") you agree to these Terms. If you don't agree, please don't use the Service.
PrepSignals summarises publicly posted GMAT debriefs and turns them into charts, cohort statistics, and a personal study plan. It is an independent study-research tool. It is not affiliated with GMAC, Reddit, GMAT Club, or any test-prep company, and it is not test-prep advice from a licensed advisor.
Everything on the Service is descriptive, not causal. Debrief statistics show what other people reported doing — they don't guarantee that any plan, resource, or tactic will change your score. Your prep decisions are your own.
You can browse without an account. To save debriefs, keep a checklist, or log progress you need a free account with a valid email address. You are responsible for keeping your password confidential and for activity under your account. You must be at least 16 years old to create an account. We may suspend or delete accounts that abuse the Service (automated scraping, attempts to access other users' data, or attempts to bypass access controls).
You keep ownership of the study data you save (your plan, saved debriefs, checklist, and progress log). You grant us permission to store and process it solely to run the Service — syncing it across your devices and showing it back to you. See the Privacy Policy for details, including how to delete your account and data.
Debrief summaries are derived from public posts on Reddit's r/GMAT and GMAT Club and always link to the original source. The original posts belong to their authors and platforms. If you are the author of a summarised post and want it removed or corrected, email prepsignals@gmail.com and we will act promptly.
Don't misuse the Service: no unauthorized access attempts, no bulk scraping of the database, no reselling of the data, and no use of the Service to send spam. We may throttle or block abusive traffic.
The Service is provided free of charge and "as is", without warranties of any kind. We may change, pause, or discontinue features at any time. We are not liable for indirect or consequential damages arising from your use of the Service; our total liability is limited to the amount you paid us (which, today, is zero).
If we make material changes we'll update the effective date above and, for account holders, note the change on the site or by email. Continuing to use the Service after a change means you accept the new Terms.

This policy explains what PrepSignals collects, why, and what control you have. The short version: anonymous use stays in your browser; an account stores your study data server-side so it can sync; analytics are aggregate; marketing email is opt-in; we never sell your data.
Nothing that identifies you. Your four score-path answers live in this browser only. We collect aggregate usage analytics (see section 4) about which pages and features are used.
When you sign up we collect your name, email address, and password. We never store your plain-text password; authentication is handled by Supabase. If you choose to provide them, we also store your target score, test month, main weak area, and prep stage, so the Service can personalise recommendations. Your saved study data — score path, saved debriefs, checklist, and progress log — is stored in our database so it syncs across your devices. We record whether you opted in to marketing email and which Terms version you accepted.
Account data is stored with Supabase (our authentication and database provider) and protected by row-level security: your data is readable only by you and by PrepSignals administration. The site is hosted on Vercel.
We use Vercel Analytics (aggregate, cookie-free page analytics) and PostHog (product analytics: which features are used, where people drop off). Anonymous visitors are not personally identified. If you log in, your product-analytics events are associated with your account so we can understand and improve the logged-in experience. We do not run third-party advertising trackers.
We send transactional email you can't opt out of while you have an account (email verification, password reset). Marketing email — prep discounts, product updates, study tips — is sent only if you opted in, and every message includes an unsubscribe link. You can change the marketing setting anytime under Account → Profile.
We use browser local storage to keep you signed in and to cache your study data on your device. We don't use advertising cookies.
You can view and edit your profile under Account → Profile. You can delete your account there too — deletion removes your profile and all saved study data from our database. You can also email prepsignals@gmail.com to request a copy or deletion of your data, and we'll respond within 30 days.
PrepSignals is not directed at children under 16, and we don't knowingly collect their data.
If this policy changes materially we'll update the effective date above and note the change on the site or by email to account holders.
