As I know, the words "Aforementioned" and "In question" have a similar meaning and imply referring to something that has already been mentioned, but when I looked up at the internet i found out that aforementioned was much more commonly used.
Let me demonstrate with an example:
"I want to apply for the English Course of X University. The aforementioned course is highly recommended because of.."
"I want to apply for the English Course of X University. The course in question is highly recommended because of.."
Is there a difference between the two sentences in terms of meaning?
aforementioned
is more formal
