"きょうしつはどこですか？"

Translation: Where is the classroom?

[kbreddit]

教室 - classroom

[Shinobusagi]

Because きょう (教) is the Sino-Japanese reading (the onyomi) of 教える (おしえる), "to teach". And しつ (室) is just "room".

[JackVincent95]

another easy but slightly more native sounding way to say this is: "教室に行きたいんですが”
Which literally means "I'd like to get to the classroom but..."
Japanese people are quite indirect and often ask for things without actually asking for them ^_^

教室は何処ですか？

[sotnosen93]

Note however that 何処/どこ is usually written in kana only.

The perpetual question.

The question I asked perpetually in college.

[Luke16187]

I wrote " Where is the class " and it wasn't accepted.

I have such a hard time remembering words when I see them in kana only. It's why I wish more kanji would be introduced at this stage.
