Application Key
VocaBi contains 3-choice questions with 5 difficulty levels. Questions are scored according to their difficulty level. Each competition progresses by answering the questions from easy to difficult within 10 seconds and ends with a wrong answer. The points received are reported in the statistics section and vocabulary development can be easily followed.

The difficulty levels of the questions are determined dynamically based on the correct answer rate of the users. Questions with a correct answer rate of over 85%, with a condition of not less than 50 answers, drop 1 level, while questions with a correct answer rate of 15% increase 1 level. (Levels cannot be lower than 1 and higher than 5)

The scores for the difficulty levels and the number of questions in each competition are as follows:

Level / Score / Number of Questions
... 1 ... / .. 10 .. / ... 4
... 2 ... / .. 20 .. / ... 5
... 3 ... / .. 30 .. / ... 7
... 4 ... / .. 40 .. / ... 10
... 5 ... / .. 50 .. / ... 20

The average of the scores is used to determine the Vocabulary Level:

Score ........ / % ....... / Level
