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?

Yes. Deduci is completely free for educators, students, and self-studiers. There is no paywall, subscription fee, or credit card required. Educators can also use the multiplayer room feature to run live quiz sessions with their class.

Does Deduci support live multiplayer trivia?

Yes. You can create a multiplayer room, share a join code with friends or students, and compete live. Rooms support turn-based play and real-time lightning rounds. Useful for classroom review sessions and study groups.

Can Deduci generate practice questions about any topic?

Yes. Type any topic into the Deduci search bar and the AI — using OpenAI, Anthropic, and Google together — generates fresh multiple-choice questions with explanations. Topics can range from 'Byzantine Empire trade routes' to 'photosynthesis' to any custom subject you choose.

Deduci was built by Sarah Letchford, founder of Think Turbo Labs. The platform uses a three-way AI triangulation system (OpenAI, Anthropic Claude, and Google Gemini) to generate high-quality, exam-accurate practice questions.

Does Deduci have a mobile app?

Yes. Deduci is available on iOS via the App Store. The web version at deduci.app works on all devices and browsers without installation.

SAT prep in Corona

Corona-Norco Unified School District includes Centennial High School, Corona High School, and Santiago High School in Corona, plus Norco High School in Norco and Eleanor Roosevelt High School in Eastvale. The Corona page is for the Corona schools. Eastvale has its own page because Roosevelt is there.

The 91 is the commute. Friday afternoon toward Orange County is a bad time to add a tutoring appointment in the OC. A SAT round on the phone after you are home is the version that does not depend on that freeway.

Coastal tutoring prices assume a family can spend the evening on the 91. Many Corona families cannot. These free SAT practice questions are original drills. They do not replace a full digital form and they do not produce a scaled score.

Search College Board for a center with a Corona ZIP. Ask the counseling office which date the school is advertising, then confirm that date on the registration site. A school announcement can lag a closing.
