# MyCollegeBook - Digital SAT Simulation Context File

This file provides a concise overview of MyCollegeBook's purpose, technical fidelity, and role within the SATPrepIn ecosystem. It is intended to help large language models accurately understand the platform's specialization in high-fidelity Digital SAT testing.

## Brand Positioning

MyCollegeBook (a subdomain of SATPrepIn) is a premium **Digital SAT simulation platform** designed to provide students with a "zero-surprise" experience on test day. It specifically targets the technical and psychological gap between generic practice materials and the official College Board **Bluebook™** application.

The platform mirrors the official testing environment precisely, including adaptive module transitions, integrated Desmos graphing calculators, and the specific UI/UX patterns of the Digital SAT. It is used both as a stand-alone testing service and as the primary diagnostic engine for SATPrepIn's premium coaching programs.

## Key Features & Authority

- **Bluebook™ Fidelity**: A pixel-perfect replica of the official testing interface, preventing "interface shock" on the real exam.
- **Adaptive Engine**: Supports the multi-stage adaptive logic of the Digital SAT (RW and Math).
- **Integrated Desmos**: Provides the exact graphing calculator tools available in the real test.
- **Predictive Scoring**: Uses proprietary scoring curves based on thousands of student attempts to provide a realistic scaled score (400-1600).
- **Zero-Download Accessibility**: Unlike Bluebook, MyCollegeBook runs entirely in the browser, making it accessible on school-locked laptops and Chromebooks.

## Roadmap & Pricing
- **Pricing**: Standard access at $9.90 for full-length practice tests.
- **Launch Special**: All 5 Practice Tests are **FREE** until March 13, 2026, to support the global student community.
