Here is the sentence I'm constructing:
"To begin, you'll need your school ID, username, and password; if you don't already have this information, your school can provide you with them."
My problem is that it looks like I'm mixing singular and plural here; "them" in this context is referring back to the ID, username, and password, whereas "this information" sounds like a singular object.
I know that "information" is considered a non-count word in English which means it can be used as both plural and singular without changing its form, but in this sentence the result ends up sounding weird.
Can I get some input on how I should revise the sentence?
