Click **"Install"** in your browser to add it to your home screen. ### Use Locally ```bash # Clone the repo git clone https://github.com/Arjunpolen/TCS-NQT-PYQ-QUESTIONS.git # Run a local preview (recommended for full PWA behavior) cd TCS-NQT-PYQ-QUESTIONS/tcs-nqt-prep-app py -m http.server 8123 # Then open http://127.0.0.1:8123/index.html ``` ### Validation Scripts ```bash # From the repo root npm run validate:content npm run test:logic ``` `validate:content` checks duplicate IDs, invalid answer indexes, missing explanations, missing hydrated metadata, and suspicious explanation/answer mismatches. `test:logic` covers the pure helper layer in `quiz-model.js` and the normalization/session helpers in `app-core.js`. ### Study from Markdown Files All questions and study materials are in plain Markdown โ€” read them directly on GitHub, in VS Code, or any text editor. --- ## ๐Ÿ“… Suggested 7-Day Prep Plan | Day | Focus Area | What to Do | |:---:|:-----------|:-----------| | 1 | Quantitative Aptitude | Solve 50+ problems on percentages, ratios, SI/CI from `pyq-300.md` | | 2 | Quantitative Aptitude | Speed-Distance, Profit-Loss, Work-Time. Review formula sheet | | 3 | Logical Reasoning | 30+ questions on series, coding-decoding, blood relations | | 4 | Verbal Ability | Learn 50 new vocabulary words. Practice RC passages | | 5 | Programming & DBMS | Pseudocode practice, SQL basics, `coding-questions-50.md` | | 6 | Coding Practice | Solve 10โ€“15 problems from `questions.md`. Review DSA patterns | | 7 | Full Mock & Revision | Take a full mock test in the app. Revise weak areas | --- ## ๐Ÿ’ฐ TCS NQT Roles & Packages | Role | Package (CTC) | NQT Score Required | |:-----|:--------------|:-------------------| | Ninja | โ‚น3.36 LPA | Qualifying score | | Digital | โ‚น7โ€“9 LPA | Higher score threshold | | Prime | โ‚น9โ€“11+ LPA | Top percentile | --- ## ๐Ÿ“š Recommended Resources - **R.S. Aggarwal** โ€” Quantitative Aptitude & Reasoning - **Word Power Made Easy** by Norman Lewis โ€” Vocabulary building - **GeeksforGeeks** โ€” Programming & DSA reference - **PrepInsta** โ€” TCS NQT specific practice - **Striver's SDE Sheet** โ€” Coding round preparation --- ## ๐Ÿ›ฃ๏ธ Phased Roadmap ### Phase 1 โ€” Completed foundation pass - Split the app into UI, content, and quiz helper layers (`app-core.js`, `app-bootstrap.js`, `content-model.js`, `quiz-model.js`) - Added adaptive quiz selection, timed presets, resumable sessions, flagged questions, confidence tracking, mistake-bank review, and explanation-first review - Added trust signals such as content versioning, reviewed dates, confidence labels, official source links, and a changelog - Added content validation and logic test scripts for lightweight engineering guardrails ### Phase 2 โ€” Next frontend/content pass - Expand the content audit based on `validate:content` warnings and add more answer-explanation consistency checks - Add richer analytics views for low-confidence answers, flagged questions, and topic recovery over time - Improve search, bookmarks, and study surfaces with more cross-links between questions, study topics, and flashcards ### Phase 3 โ€” Product hardening - Add a proper release checklist for content freshness, PWA smoke checks, and offline cache validation - Introduce structured content authoring conventions so new questions and notes stay consistent - Add more targeted test coverage for schedule generation, analytics summaries, and review queue behavior ### Phase 4 โ€” Deferred architectural review - Backend sync, multi-device accounts, and collaboration features are intentionally deferred for a later review - A TypeScript migration is also deferred until the current browser-side architecture and content model settle --- ## ๐Ÿค Contributing Contributions are welcome!
