About this study beta
Support and operator
Lexicon is operated by sqdevelopers. For study-app help, content corrections or privacy requests, email qasimashah@gmail.com. For a content correction, include the app name and question ID.
Lexicon provides original GRE lessons, practice questions, timed forms, flashcards and review tools. The material remains an editorial draft awaiting qualified subject review and learner validation. Use official preparation materials alongside it.
Workspace and price
The $10 USD/month membership covers saved plans, official-result references and notes, and creating or editing personal flashcard collections. Original editorial draft lessons, questions, forms and card practice stay free. Existing work remains readable, reviewable and exportable after membership ends. Each app has its own subscription; official resources and tutoring are not included. Check current availability and workspace limits. See subscription, cancellation and refund details before subscribing.
What the results mean
Practice results are raw accuracy on our original items. They are not an official scaled score or a validated score prediction. Difficulty labels are author estimates. Related question families recur, and drills reuse full-form items; a retake is not a fresh independent assessment. Writing receives a self-review checklist, not a scored human evaluation.
These GRE forms use fixed sections. They do not reproduce the real test’s section-adaptive routing.
We have ten full-length forms. Their timing and question formats follow the published exam outline, but the apps do not reproduce official proctoring, all interface behavior or certified accommodations. Full-duration learner trials and assistive-technology testing remain pending.
Privacy and saved work
ChatGPT sign-in supplies a Site-specific account identifier and account display details. The Site uses that identifier to keep each learner’s stored study work separate. Saved data includes answers, drafts, progress, notes, settings, reports and any results you choose to enter. Hosting and sign-in are provided by Sites/OpenAI and Cloudflare. When subscriptions are available, membership is managed by Stripe; card information is entered with Stripe rather than stored in this study app.
You can download course and flashcard records from Account. Course exports temporarily omit protected results during timed or unrevealed practice. The latest 30 practice, ten full-exam and ten writing sessions are retained; regularly export older work. Account also lets you clear your saved course work. A blank profile with an account identifier and revision counter remains to prevent delayed saves from restoring cleared work. That action does not erase flashcard records, a ChatGPT account or provider backups, and does not cancel a subscription.
Report a content problem
After opening feedback, use “Report a content concern” to save its question ID, category and your description in your account and export. This records a concern with your study history; it does not send a direct message or guarantee staff review. Do not put contact, medical, financial or other sensitive personal information in a report.
