How do you study when you are alone?
How do you study when you are in a group?
I prefer to study alone with a guidebook. After practicing on my own I ask my native speaker friends to correct my work on paper and then after I study alone again.
I feel like I only gain from group activities when I am doing speaking practice. But, when it comes to grammar I learn best on my own with a resource book.
Everybody learns in different ways.
