나만의 오답노트 - My OdapNote

This app is based on the'Incorrect Answer Note' function to save time, organize incorrect answers more efficiently, and provide convenience so that you can easily open and check them anytime, anywhere. You can maximize the efficiency and convenience of study time through this app instead of the incorrect answer note that you have to write by hand by entering each subject folder, taking a picture, and saving it.
The purpose of this is to provide a function that allows you to sort out incorrect answers by subject by simply taking pictures through this app without the need to manually type the problem or create a separate folder in the phone gallery to organize the pictures taken.
