A: a lot of people are complaining about Prof Balle's lectures. They say he goes over the materials too quickly in class. What do you think?
B: well, I don't have to write as many notes as most students in there. You see, I have similar course in another score. Maybe I'm not the best person to ask.

What does "another score" mean? Or maybe it is the word "score"?

thank u in ad:)
Not a native and not 100% sure... But it seems the word 'score' can have a general meaning very similar to 'matter' or 'concern'.
There is for instance the expression 'on that score' that means 'regarding this concern or matter'.
Hope this helps ?
There is a possibility that they are music students and are talking about 'musical score.'

From Cambridge Dictionary:
musical score: a written form of a musical composition; parts for different instruments appear on separate staves on large pages; "he studied the score of the sonata"
Students: We have free audio pronunciation exercises.
Kolndom You see, I have similar course in another score.

I don't recognize such a phrase at all. Where does it come from? Are you sure it's not-- 'You see, I've had a similar course in another school'?

Thank u, davkett! Emotion: smile

U are right!

I got it from TOEFL listening test. And i think i failed to differentiate "school" from "score", which caused the problem.
