1. Download the ‘Study 100’ APP from Google Play Store and App Store.
(Available on tablet and mobile, but tablet use is recommended.)
2. Log in as an integrated faculty member and create learner information by entering nickname and grade.
(Once you create a learner, the grade cannot be modified. If you want to study a different grade, please create additional learner information.)
3. You can learn concepts through ‘meticulous conceptual learning’ and build your skills through ‘solid basic problems’ and ‘challenging advanced problems’. Lastly, check your skills by taking the ‘End of Unit Evaluation’.
4. Lecture videos are also provided for ‘Meticulous Concept Learning’, ‘Solid Basic Problems’, and ‘Challenging Advanced Problems’, so you can learn anything you don’t know by listening to the lectures.

6. Improve your skills by re-solving the questions you got wrong using the incorrect answer note.
7. You can check your learning progress and learning results in the learning status.
8. I feel a sense of accomplishment by checking how much I have learned every day on the learning calendar.
