Han Completed Her Red Level 1 Swimming

After 5 refreshing lessons, Han completed her Red Level 1 today and is upgraded to Red Level 2 in her next swim lesson. I observed her during the previous few lessons that she did not pay attention to her teacher and always wondering. She always does not focus on the things she does including her study and school works. Is this her in-born character or the result of the wrong methods we educated her ?
