Courses, practice and guides.
Six months. One payment.

No. Premium includes every published course and its exercises, alongside the question bank, concept library and PDF guides. Online access lasts six months from confirmed payment. Downloaded PDF guides and toolkits are yours to keep.

Yes. Every course has public sample lessons, with additional lessons available through a free account. Open Courses to compare the syllabuses and read a sample. The lesson list identifies which parts require Premium.

Each signed-in account, Premium included, can open up to 150 answers and 120 concept lessons an hour. Reopening something within 60 seconds does not count again. If you reach the limit, a message tells you when the hour resets.

No. One payment buys six months. No card is kept on file and there is no subscription to cancel.

Tell us on the contact page and we will extend your access past the interview date at no charge. The same goes for a failed payment or an answer that looks wrong: send it in, and someone will reply.

Your account goes back to the free tier with its progress and bookmarks intact. Another six months is only ever bought on purpose.

You see one price, set by the country you are in. In India it is ₹2,000, paid by UPI, card or another method shown at checkout. Everywhere else it is US$25, paid by card, Apple Pay, Google Pay or another method available in your country. Both buy the same Premium. Dodo Payments runs the checkout as merchant of record: it collects your payment details, charges any tax that applies within the listed price, and sends your receipt. Premium is added to your Google account once our server confirms the payment with Dodo Payments.

Yes. 5 answers per topic are open to anyone, and 9 once you sign in for free. They are complete, with the same scoring rubrics and follow-ups as the Premium ones, so you can judge the quality first.

Not for a change of mind. Everything opens the instant you pay, so sales are final except where the law where you live requires a refund; the Terms explain the details. The open answers in every topic are written to the same standard as the rest; read them first and buy only if they are clearly worth it to you.
