Click here for feature list
▼A grade sheet that allows you to set goals
- By setting a goal for the number of questions you want to study in a week, you can continue studying systematically.
-Display the degree of achievement towards the goal in a pie chart.
- Displays a list of daily studies in a bar graph.
▼There are 3 courses: “by exam”, “by unit”, and “mock exam”
・"Examination-specific course" is a course where you practice past questions for each exam. You can solve the questions asked in each exam.
- "Unit-specific course" allows you to solve past questions by dividing them into units. Solving similar problems together, such as calculation problems and legal problems, will definitely deepen your understanding.
・The "mock test course" is a course created for final adjustments for the actual test. The questions are arranged evenly from each unit, allowing you to test your skills in preparation for the actual exam.
▼There are 4 modes: “Normal”, “Shuffle”, “Not Implemented”, and “Miss”
- In "Normal mode", you can practice in the same order every time, so you can study in a good rhythm, but it also has the disadvantage of memorizing the answers in order.
- In "Shuffle mode", the questions are the same as in normal mode, but the order in which they are asked is randomized. This prevents you from memorizing the answers in the order of the questions.
・In "unsolved mode", you can only solve problems that have not been solved so far. Specifically, only the questions with gray sticky notes are selected and asked.
・"Miss mode" is a mode in which you choose a sticky note with a red or yellow color. When you solve a problem, the sticky note is automatically colored (correct answer → blue, incorrect answer → red). You can also change the "sticky" color to your favorite color at that time.
It also has a function to attach sticky notes!
Learn efficiently with a study method that suits you.
Come on! Let's start studying to pass!
