Executive Summary

ANALYST: COI RESEARCH

Application of Transformer-based deep learning models to predict a student's TOEIC test score with 90% accuracy after just a few questions, and generating a personalized study path to maximize score gain.

rate_review Analyst Verdict

"Demonstrates the efficiency of 'Knowledge Tracing'. Unlike rule-based adaptive learning, deep learning (Transformers) finds hidden correlations in user behavior, allowing it to eliminate 90% of unnecessary study questions."

warning The Challenge

Standard test prep (TOEIC, SAT) is inefficient. Students waste time answering questions they already know or questions that are too difficult. Traditional adaptive algorithms were too simple to capture the complex dependency between different grammatical concepts.

psychology The Solution

Built 'Santa', an AI tutor powered by a proprietary Transformer model. It analyzes the student's interaction data (time per question, choice patterns). After a 10-question diagnostic, it predicts their final score. It then serves only the questions that have the highest probability of increasing that score, ignoring what the student has already mastered.
