Wrongbook is an independent study tool made by a student. It is not affiliated with, endorsed by, sponsored by, or connected to the China Scholarship Council, the Ministry of Education of the People's Republic of China, or any other body that administers the CSCA exam.

“CSCA” is used here only to say which exam this tool helps you prepare for. The official source for exam rules, dates, registration and results is the examination body itself — always confirm there, not here.

Wrongbook is run by an individual (Calin Nedelcu, Romania) as a personal project, not by a company. It is free, there is nothing to buy, and no payment details are ever requested.

• Use it for your own exam preparation.
• Don't scrape, bulk-copy, resell or redistribute the questions, explanations or any other content.
• Don't attempt to disrupt, overload or break into the service.
• Keep your sign-in codes to yourself — anyone with a valid code can reach your account.

Accounts that abuse the service may be suspended or removed.

Every practice question, explanation and note is original work written for this app, and remains the author's. You may use it to study; you may not republish it or build a competing question bank from it.

Your own study data — your answers, mistakes and progress — is yours.

Practice material is written and machine-checked with care but may still contain mistakes, and the readiness and projected-score figures are internal estimates, not predictions. Using Wrongbook does not guarantee any particular exam outcome.

The service is provided “as is” and “as available”, without warranties of any kind, and may change or stop at any time. To the fullest extent permitted by law, the author is not liable for any loss arising from your use of, or inability to use, the service.

Nothing here limits rights you have as a consumer under mandatory law, or liability that cannot legally be excluded.

These terms are governed by Romanian law. If you are a consumer resident in the EEA, you keep the protection of the mandatory rules of your own country and may bring proceedings there.

These terms may be updated; material changes are reflected in the “last updated” date above. Continuing to use Wrongbook after a change means you accept the updated terms. If you don't, delete your account from the Account page.
