What 1500prep is
1500prep generates SAT Math practice questions, checks your answers, and shows which question types you are getting wrong. It is run by one person and is in early access: it is free for now, and things change often.
SAT is a trademark of the College Board, which is not involved with 1500prep and does not endorse it. Questions here are written to resemble the exam; no real exam question is reproduced.
What we store
- Your name and email address, and a password that is stored only as a hash.
- The worksheets you are given, the answers you submit, whether each was right, and the results built from them.
- If a tutor adds you as their student: the name, and optionally the email, target score and note they enter about you.
That is all. There is no analytics, no advertising, and no tracking of what you do on other sites. The only cookie is the one that keeps you logged in.
Who else sees it
- Supabase stores the database and handles logins. The database is hosted in Mumbai, India.
- Vercel runs the site itself.
- Anthropic generates the questions. Only the topic, difficulty and, when you ask for more like a question, that question is sent. Your name, your email and your answers are never sent.
- An email provider delivers account emails such as password resets.
Nothing is sold or shared with anyone else.
Student links
A student added by a tutor gets a private link instead of an account, so no email or password is collected from them. Anyone who has that link can see and answer that student's worksheets, so it should not be shared. A tutor can reset a link at any time, which immediately stops the old one from working.
Your choices
Write to sinankupeliai@gmail.com to get a copy of your data, correct it, or have your account and everything in it deleted. Deletion is permanent and includes your worksheets and results.
Using 1500prep
- Keep your password to yourself; you are responsible for what your account does.
- Don't try to break, overload, or scrape the service. Question generation is limited per account, and those limits exist to keep it running.
- Questions and answers are generated by a language model and reviewed in batches, not one by one. Mistakes are possible, so treat the answer key as a study aid rather than a final authority, and tell us when something looks wrong.
- The service is provided as it is, with no promise of a particular score or result, and it may be unavailable at times.
Payment
1500prep is free while in early access. If paid plans arrive, you will be told before anything is charged, and nothing you already have will start costing money without your agreement.
Changes
