What is the meaning of parentheses in a legally binding contract?

Question by player41140: What is the meaning of parentheses in a legally binding contract?
There is a contract that says, “The scholar must obtain at least 60 ECTS (30 US credits).”

Does this mean the scholar must have at least:

-60 ECTS and 30 US credits
-60 ECTS and/or 30 US credits
-60 ECTS or 30 US credits

or does it mean something else?

Thanks!
