In every one hour of [an] English lesson, I have no difficulty [understanding] what [the] tutors say.
I can respond [to] them almost as quickly [in English] as when I speak in Japanese. But when it comes to accuracy, [it is the] worse. Although I know "fluency" is a key to [connecting] with others, what's [most important is] to improve accuracy. If [the] structure of [grammar] is broken as I speak English, [then my communication] makes no sense. My favorite tutor once said, "[focus] on accuracy; fluency eventually follows". I totally agree [with] that. I would like to [speak] English with perfectly correct [grammar], even if [I am overly expressive]. Sophisticated English can [demonstrate] the [level of dedication one has put in to learn]. I'm [grateful that my English is understood], despite a few mistakes.
