Is there a free diagnostic quiz for AWS certification on Deduci?

Yes. The AWS Cloud Practitioner and Developer Associate diagnostics are 65 questions, the length AWS publishes. You get a percent correct on four-choice scenarios with one best answer. It is not a pass or the AWS scaled score. Start a round without an account. Create an account for fewer repeated questions and progress tracking.

Does Deduci offer free CompTIA practice tests?

Yes. Deduci has free practice tests for CompTIA Security+, Network+, A+ Core 1, A+ Core 2, Project+, and IT Fundamentals. The diagnostic runs up to the maximum CompTIA publishes: 90 questions, or 70 for IT Fundamentals. The result is a percent correct, not a pass or a scaled score. A five-question practice round is a separate short drill.

How does the free Deduci diagnostic quiz work?

Choose an exam, then start the full-length diagnostic. It is long enough to read as a rough percent correct, in a format close to that exam. It is not a guarantee of a pass and not an official score. A five-question practice round stays available as a short drill.

Where can I take a free practice test?

Deduci publishes free practice tests for AWS Cloud Practitioner (CLF-C02), AWS Developer Associate (DVA-C02), AWS Solutions Architect, CompTIA Security+, CompTIA Network+, CompTIA A+ Core 1, CompTIA A+ Core 2, CompTIA Project+ (PK0-005), CompTIA IT Fundamentals (Tech+ FC0-U71), Cisco CCNA (200-301), LSAT, GRE, ACT, GED, and C/C++ certification. Each round is dynamic and skill-based: a miss comes back. The diagnostic is a full sitting and the result is a percent correct, not a pass. Start a round without an account. Create an account for fewer repeated questions and progress tracking.

Is Deduci free for educators and students?

Does Deduci support live multiplayer trivia?

Questions

What is a vocabulary study quiz on Deduci?

A short multiple-choice round on words, or a listen-and-tap round for Spanish, French, German, or Italian. You practice the ones you miss.
