Pricing
You can read tracks, articles, and the roadmap without paying. You pay when you want to run code against the tests, get AI review, and keep the extras we add for individuals later. Prices are USD, and INR for buyers in India. Until 31 Dec 2026 we are running a promo. Monthly is $3 instead of $5. Yearly is $36 instead of $60. Lifetime is $149 instead of $299. Interview Prep, sold separately, is $79 instead of $149.
Paying from India? Switch to INR for UPI, netbanking and wallets. USD takes international cards only.
Currencies other than USD and INR are estimates, charged in USD, at ballpark mid market rates from Frankfurter, cached on our side. Page copy last checked September 18, 2026.

One payment. Access until the end date, about a year. Cheaper than $60 of monthly list.

Its own product with its own questions: the C screen, bit manipulation under time, reading disassembly, and debugging broken programs, on a server-side clock with timed role mocks and a debrief. Not part of Monthly or Yearly; Lifetime includes it, and so does every plan bought before Interview Prep was sold on its own. The first question in each module is free to try. See the questions.
$29 / seat / year
Minimum 5 seats ($145 / year). Shared progress for a class, bootcamp, or engineering group. Billed once a year.
