Trouble connecting sounds to meanings

In every language, not just Japanese, reading and listening are separate skills, and are measured differently. That’s essentially your difficulty, as connecting sounds to meanings is precisely what listening is. You won’t get better at listening through practicing reading, as stated above. But since you know both the sounds and the meanings, just doing the connection shouldn’t be too much harder.

Also, the self-study quizz extension is awesome because it includes sound to meaning exercises!
