It asks one question at a time, assesses a learner’s answer, gives a concise correction, and moves on with a follow-up—an approach intended to make spontaneous concept recall feel more like a technical viva or campus interview.
How a practice session works
The app’s core is a repeating question-and-feedback loop:
As an Amazon Associate I earn from qualifying purchases.
- Answer a focused question. The learner responds to one prompt rather than working through a long quiz.
- Review the verdict. The app labels the response Correct, Partially Correct, or Needs Work.
- Read a short correction. If the answer is incomplete or mistaken, the app offers a concise explanation.
- Try a follow-up. It asks another probing question to keep the practice moving.
This format is aimed at active recall: explaining a concept in your own words and responding to the next question, rather than only rereading notes. Learners can answer aloud for oral practice or type their responses into the interface.

How the project was built
Author Ankit Mishra says he built the app for a friend preparing for college technical vivas and campus interview rounds. His project article identifies Google Gemma 2 (9B-IT) as the model and Python, Streamlit, and Render as the tools used for the interface and hosting. These are the author’s descriptions of the implementation; they do not independently establish the current state of the code or whether the hosted demo remains available.
Rank #2
- Updated test materials for applicants who filed on or after October 20, 2025.
- Includes cards covering all 128 civics questions and answers, with illustrations to support easier memorization. Enhanced with historical photos, facts and symbols.
- Includes cards with assembled sentences for the English proficiency test.
- Full deck covers both texts that you will have to take for your Naturalization.
- A 100-question civics deck is also available for applicants who filed before October 20, 2025.
What the feedback can—and cannot—tell you
The author reports that his friend found the brief corrections and immediate next question helpful, describing the experience as “a realistic viva without the anxiety.” That is one user’s reported reaction, not a measured learning outcome. The available account does not establish the app’s grading accuracy, its effect on exam results, or how well it performs across different learners.

Check AI feedback against course material
Gemma’s official documentation cautions that the model can hallucinate. That matters in a practice examiner: a generated question may be misleading, and a verdict or correction may be wrong or incomplete. Treat the feedback as a prompt for review, not as an authoritative answer key. When an answer affects your understanding, verify it against a trusted textbook, lecture notes, or instructor-provided material.
Rank #3

Practical limits to consider
The project description presents the app as an open-source viva drill and discusses the possibility of local inference, but those statements do not establish the repository’s current license or code state, or that the present demo can run locally. The available information also does not establish whether answers are retained or sent to a hosted model, or what privacy, security, accessibility, and uptime protections currently apply. Check the project’s current repository and service details before sharing sensitive information or relying on the demo for a scheduled study session.
