소규모 학원 CBT 자체 개발 불가 — 개발 3-6개월·수천만원 소요

Problem

As national certification exams transition to CBT, test takers want mock exams that replicate the actual test environment (timer, screen layout, marking method). However, small academies or solo edutech apps would need 3-6 months of frontend development and tens of millions of KRW to build a CBT simulator themselves, so most give up.

Solution

Inserting a single line of JavaScript widget code embeds a test environment identical to the actual CBT into the academy's website or app. Uploading a question bank JSON immediately deploys a CBT mock exam. As more academies use the widget, UI/UX improvement data and test statistics benchmarks become richer.

Target: Small certification academy owners, solo edutech developers — small businesses needing to respond to CBT transition
Revenue Model: Monthly 49,000 KRW (approx. $37) basic (500 test takers) + 100 KRW (approx. $0.08) per additional test taker — Free tier: 50 test takers per month free
