In English, "100 points" can be expressed as "a perfect score" or "a full score." This comes from the traditional grading system in which a score of 100 out of 100 is considered to be the highest possible grade or score. Here are some examples of how you can use this phrase in a sentence:

"She got a perfect score on her math test." (她数学考试得了满分。)

"He scored a full score on the English exam." (他英语考试得了满分。)

"The team's performance earned them a perfect score from the judges." (球队的表现获得了评委们的满分。)
