日本語と韓国語を勉強しています

私は日本語を勉強しています。８月までにどれくらい話せるか分かりません。でも、がんばります。日本に行く前に、何か準備が必要ですか？

私は韓国語も勉強しています。日本人の友達は韓国語が上手です。でも、「私はあまり上手じゃない」と言います。彼女は韓国語を教えるのが難しいと言います。

I’m trying to keep the fact that I’m studying Japanese a secret because I want to surprise my Japanese friend. I’m curious to know what level of fluency I could reach in Japanese by August, as I’ll be visiting her in Japan at that time. Is there anything I should be aware of or prepare for before going to Japan? I want to do my best. My friend knows that I’m studying Korean but doesn’t know that I’m also studying Japanese. She’s quite fluent in Korean, though she insists she isn’t, which I disagree with. She does have some difficulty teaching me Korean because she’s not sure how much to go through with me in each FaceTime session, and I’m unsure myself.
