<aside> 💡 1️⃣ If you make good use of the app, your study methods will become more convenient and efficient. Try using the app with the content below. 2️⃣ Each worksheet’s orientation is prepared at the very beginning of the first lesson in each course. Make sure to check it before starting your studies. :)

📌 This guide is based on iPad usage. Android-based devices (e.g., Galaxy Tab) work in almost the same way. On smartphones, due to the small screen size, it may be difficult to view textbooks and take lessons at the same time. (You may only be able to do one—either view the textbooks or watch the lesson.)
