Features & Capabilities

Are you worried that high school English has suddenly become more difficult?
Different from junior high school English, the English language is complex, with long, drawn-out sentences.
"I can't keep up with the classes," "My test scores have dropped,"
This English learning app was created for first-year high school students to help them avoid giving up.

Kokoei is more than just a problem-solving app.
It provides detailed, thorough explanations of why things happen, as if a teacher were standing next to you.

[Three Strengths of Kokoei]

📖 1. Easy-to-understand explanations without technical terms
"Relative pronouns," "past perfect subjunctive"... We don't just explain things with complex terms.
All grammatical terms are explained in a digestible way, with abundant Japanese translations and illustrations (such as subject-verb structure diagrams) to help you understand intuitively.

⚠️ 2. Thoroughly Address Common Mistakes
"Forgetting the third-person singular s" and "Mixing up be verbs with regular verbs"
Compare common stumbling points for high school students with "❌ Bad Examples" and "✅ Good Examples."
Prevent mistakes that will result in points being deducted on tests.

✍️ 3. Abundant Quiz Formats for Solidification
Multiple-Choice Questions: Review basic rules
Rearrangements: Develop a sense of English word order
* Fill-in-the-Blank: Practice vocabulary and conjugation
Instead of simply answering "true or false," every question comes with a detailed explanation of why that answer is correct.
