Feature 1 Repeated learning focusing on 400 frequently occurring words
According to the forgetting curve of Ebbinghaus, more than half of what I learned is forgotten in one hour. It is effective to repeat it many times without forgetting to fix the memory.
In order to maximize the effect of the English idiom Sister, I narrowed it down to "essential English idioms that tend to be ambiguous". As you look at the same idioms over and over again, you will naturally remember them.

Feature 2 Surely settled by learning 3 patterns of English-Japanese, Japanese-English, and combination
Learning with the English phrasebook is often memorized by the order of words and pages, and in fact it is not remembered properly.
In English idiom Sister, we have prepared learning methods for patterns different from English-Japanese, Japanese-English, and combinations. Since the questions are random questions, they will be different each time, and you will be asked for reliable memorization ability.
