My English score improved! Prticularly, writing skill and speaking skill.
I realized that writing something on Lang-8 is so effective to enhance writing skill.
I hesitated to write my opinion and my daily life in English to public before because my English skill is not very good.
I also realized that I need not hesitate after reading many compositions of my friends on Lang-8.
They are not afraid to make mistakes.
I will keep up learning English more intensively.
