ご質問ありがとうございます。
「今年の」＝「of this year」
「前半」＝「the first half」
「不調で」＝「didn't go well」
「後半」＝「the second half」
「充実してた」＝「has been perfect」
「has been perfect」の代わりに「has been going well」と言うのも普通です。
フレーズの前半は過去形で「didn't」を使います。後半の場合では現在完了形の「has been」になります。
例文：
A：How has this year been?
今年はどんな年だった？
B：The first half of this year didn't go well, but the second half has been perfect.
今年の前半は不調で後半は充実してたよ。
ご参考になれば幸いです。
