Frequently asked questions
What does Premium include beyond the problem bank?▼
Premium adds full-length role-based OAs with saved reports and question review, all available firm-matched mock sessions, complete access across 14 learning paths, full Speed Math tests, market-making configurations, assessment modes, Premium firm-preparation activities, and broader performance analytics and session history.
What can I use for free?▼
Free includes 115 selected problems with editorials after an attempt and Python or C++ execution, the first lesson in each of 14 learning paths, short samples of all three role-based OAs, Classic Speed Math, Dice Market Making, samples of advanced modes, public firm guides, and a mock-interview format and report preview. No credit card is required.
Are the OA simulators or mock interviews exact copies of firm assessments?▼
No. They are QuantReady practice simulations, not copies of proprietary assessments. OA structures are modeled on candidate-reported formats, and firm-matched mock rounds use public evidence where available. Actual processes vary by role, office, and year. QuantReady is not affiliated with or endorsed by the firms.
What gets saved with Premium?▼
Signed-in users can already save problem progress, submissions, code drafts, eligible Speed Math and market-making sessions, and OA sample summaries they choose to preserve. Premium adds access to saved full-OA reports and broader Speed Math and market-making history and analytics while the subscription is active. Completed mock interviews show a per-round report and contribute to preparation progress, but there is no separate mock-interview history page.
Can I cancel anytime?▼
Yes. You can cancel through the Stripe billing portal. When cancellation is scheduled for the end of the billing period, Premium access continues until that paid period ends.
What is the difference between monthly and annual?▼
Both plans include the same Premium features. Monthly is billed each month. Annual is billed once per year, and the plan selector shows its monthly equivalent and current savings using live Stripe prices. Promotional offers, when available, apply to the monthly plan only.
What payment methods are accepted?▼
Card payments are processed securely through Stripe. Available card options may depend on your country and the settings Stripe presents at checkout.
Train the complete process, not one question type.
Use Free to build your foundation. Choose Premium when you are ready for full-length simulations, complete preparation paths, and saved performance history.
