この点数は、こないだくれたプレゼントのおかえしだよ。
These points are in return for the present you gave me.
「どうしてそのテストでこんなに低い点数をとったの？」「欠席のせい。つまり、僕の隣の席の子が休んでたんだよ。」
"Why did you get such a low grade on that test?" "Because of absences. I mean, the kid who sits next to me was absent."
The number of points is how many points there are (aka the score).
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
