DÊ RESPOSTAS - English

This is a large question. I guess it depends on the person.

This leads to other questions:
- Number of words per day for how many days?

If you try to memorize 50 words a day for 5 days.

- Day 1: learn 50 new words
- Day 2: learn 50 new words and review 50 old words
- Day 3: learn 50 new words and review 100 old words

etc ...

- Being able to remember the words after how long?

Depending on the method you will use to learn the words, they will remain in your memory for a more or less long time...

Here is an interesting article on that topic :
