🚀 GATE CSE 2027 Command Center

A modern, local-first preparation hub engineered for GATE Computer Science & Information Technology (CSE) 2027 aspirants adhering strictly to the official IIT Madras syllabus and TCS iON exam mechanics.

---

💡 Overview

GATE CSE 2027 Command Center is built to address the core challenges faced by GATE aspirants: loss of negative marks, ineffective revision of weak concepts, and lack of realistic exam interface simulation.

With zero backend requirements, all user progress, mock test histories, custom test configurations, and spaced repetition data are stored directly inside your browser's IndexedDB, guaranteeing lightning-fast performance and full offline availability.

✨ Key Features

⚡ 30-Year Previous Year Question (PYQ) Engine (1995–2026)

• Official Question Types Supported:
  • MCQ (Multiple Choice Questions): Exact negative marking enforcement ($-1/3$ for 1-mark questions, $-2/3$ for 2-mark questions).
  • MSQ (Multiple Select Questions): Multi-selection evaluation without negative marking or partial credit, matching official GATE rules.
  • NAT (Numerical Answer Type): Exact string & floating-point range evaluation (e.g., $3.14 \pm 0.02$).
• LaTeX Math Rendering: Instant, crisp mathematical equations rendered via KaTeX.

🧠 SM-2 Spaced Repetition Error Vault

• Powered by the industry-standard SuperMemo-2 (SM-2) algorithm.
• Incorrectly answered or flagged questions automatically populate your Error Vault.
• Smart revision intervals ($1, 3, 7, 21$ days) calculate intervals based on quality of recall to ensure long-term retention before exam day.

🧮 Official GATE Virtual Scientific Calculator

• On-screen virtual keypad recreating the exact layout and operational constraints of the official TCS iON calculator used in GATE examination halls.

📊 High-Risk Performance Analytics

• Track overall accuracy, total marks awarded, and marks lost to negative penalties.
• Subject-by-subject accuracy heatmaps across all 11 GATE CSE sections.
• Target score predictor and performance velocity trends.

🗺️ IIT Madras 2027 Syllabus & Strategy Planner

• Detailed breakdown of all 11 official syllabus sections.
• Interactive study targets, weightage tracking, and high-yield topic priority matrix.

🔒 100% Local-First Architecture

• Built on Dexie.js (IndexedDB).
• Complete data privacy: no user tracking, no sign-ups required, works offline.
