Which do you like group lessons or online lesson one on one? I have studied English seriously for over 4 years, but I can't speak English fluently yet.
I have joined some group lessons in some English conversation schools on and off, I have tried taking part in a meet up group and taking an English lesson in an English cafe.

I thought  why I can't speak English fluently, and I realized I'm poor at speaking English with multiple people. I'm afraid making mistakes, and I tend to compare myself with other English learners. Then I started using some language exchange apps about three years before.

I met a lot of friendly and kind language exchange friends there, and I wanted to share my interests, our culture, my thoughts, and so on. I decided taking American professional English teacher's lessons. He solved my all questions, helped my pronunciations, shared our culture and customs, and so on.

I started a group chat again, but I felt it was not fun. The number is more and more, our interests are different. I'm afraid of interrupting someone's conversation, I try to express different from others, I always try to speak something, but not speak too much.I need motivation, speaking skill, passion, knowledge about many kinds of topic, many vocabulary, and so on.
I definitely like online lesson one on one.
