Let's work it out together! English is no rocket science and anyone can start speaking in English in no time. May be the reason you don't want to go to group classes is because you are shy and scared of making mistakes in front of others, but one-one discussions are the best trouble shooters for that. Apart from studying it's the best way for a cultural exchange too. I can converse in Japanese, so don't worry about the explanations.Let's enjoy our lessons to the fullest!
