Made for English Program students who study in English but revise from Thai books. Math follows the Thai IPST (สสวท.) curriculum chapter by chapter — junior high (M.1–M.3) and senior high (M.4–M.6: sets, logic, functions, trigonometry, sequences, probability, statistics) — English covers the grammar for each level up to conditionals, passive and relative clauses, and Science is quizzed in English the way your exams ask it, with physics, chemistry and biology for senior high. And because most EP students find ภาษาไทย their hardest subject, there is a full Thai-language track — หลักภาษา ม.1–ม.3 ตามหลักสูตรแกนกลาง ถามตอบเป็นภาษาไทยเหมือนข้อสอบจริง (ผันวรรณยุกต์ สะกดคำ ราชาศัพท์ สำนวน). Every topic: a vocabulary table, a short lesson, then a boss battle 👾 — answer correctly to hit the boss, 4 hearts, up to ⭐⭐⭐ per stage. New random questions every round, full solutions for every question.
