Getting good grades in school with 成績

Kanji Explanation: Becoming and accomplishing with 成

Yukari stops by the preschool where Mina works, just as Takagi is there picking up her daughter. Yukari compares her life with theirs.

ユカリ:: 「高木(たかぎ)ちゃんは成績(せいせき)よくて　しっかりしてたし、」; “Takagi-chan got good grades and had it together.”; 「ミナは料理(りょうり)が得意(とくい)だったりするじゃない。」; “And Mina's good at cooking, right?”

Key Points

成績(せいせき) means grades or performance results
- In school contexts, 成績(せいせき) usually means overall grades or academic performance.
- It is broader than one single test score.
成績(せいせき)よくて is a casual shortening of 成績(せいせき)がよくて
- The subject marker が is omitted in natural speech.
- 〜て links two qualities together, so she is saying Takagi got good grades and was dependable.
The second line softens the comparison with shared-ground language
- 〜じゃない here is not a real question but a reminder that the listener already knows this.
- 〜たりする makes Mina’s cooking skill sound like one example among her good points.
