Differences in scoring symbols between Japan, USA and China...

Yeah, Japan always stands out with its unique touches, using the gentle ○ (maru) for correct answers feels so much more wholesome and affirming than a sharp check mark. Their writing system, with those elegant kanji, hiragana, and katakana flowing together, carries the same special cultural depth and beauty.

For the U.S incorrect is just an X

💮はなまる（花丸） 💯、 Very good、Good Job、 Excellent Mark

In Japan, ○ means correct and ✕ means wrong. In the U.S., ✓ signals correct, and X means wrong. In China, ✓ is also correct, but notation styles around partial credit differ.
