Overview
A freelance solo project for a SAT prep center in Vietnam, building an e-learning platform for the center's own students to practice for the SAT — combining a Bluebook-style digital exam simulator with AI-assisted study tools and a full content-management backend for instructors.
Context & Problem
The client — a Vietnamese SAT prep center — came to me directly with a clear reference point: they wanted something close to Bluebook, the official digital SAT testing app, so students could practice in an environment that closely mirrors the real exam rather than generic quiz software.
Their stated pain points:
- No easy, structured way for their students to practice SAT questions digitally.
- Digital practice tests needed to simulate the real exam experience, not just be a loose set of questions.
- Students needed built-in AI support to understand why an answer is correct, plus a searchable knowledge base for review — not just a test with a score at the end.
The Approach
Solo freelance engagement, working directly from the client's requirements and the Bluebook reference rather than a formal discovery phase. Designed for two distinct users on one platform: the student, practicing and reviewing at their own pace, and the center's instructors/admins, who need to create and organize test content at scale.
Design Solutions
- Exam-Realistic Practice Flow (Student)
A test-taking interface modeled on the real SAT digital format — one question at a time, official-style reading passages and multiple choice, previous/next navigation — so the practice experience itself builds familiarity with the actual exam, not just the content.
- AI-Assisted Review (Student)
Every practice question includes an AI-generated explanation of the correct answer. A dedicated vocabulary system lets students build their own word bank, review it as flashcards, test themselves, and get AI-written definitions and usage notes — plus an error log that resurfaces past mistakes for targeted review.
- Structured Content Management (Admin)
Instructors manage content through a clear hierarchy — Course → Class → Week → Assignment → Question — backed by a shared question bank and test-set library so questions can be reused across multiple classes instead of rebuilt from scratch each time.
Results & Feedback
Note: I don't have exact figures or direct feedback confirmed for this project — the following is a general, unverified description, not measured outcomes.
The platform is live and in use at the center. Its purpose is deliberately scoped: it helps students get comfortable with the exam format and gives them an easy way to practice and review — the actual studying and retention is still on the student. The AI explanations and vocabulary tools exist to lower the friction of that self-study, not replace it.
