I Noticed a Mistake on my Application Really Late... HELP

So I got accepted to a CSU back in March and it is currently May. I got an email about having conditional admission to the school so I decided to check on what I self reported in the academic history portion of my application. Turns out, I listed one of my classes in the 11th grade under the wrong name. I put H Am Comp as a year long class (I got Bs) because I thought that it was one class but I didn’t know that the title of the course changed for second semester. So I needed to put one semester of H Am Comp and one semester of H Contemp Comp instead of two semesters of H Am Comp. I got the grades correct, just the course title wrong. What should I do?? Is it too late to do something?? I already got accepted and paid for housing and what not so I am afraid that I’ll get rescinded or something for my transcript not being accurate to what I self-reported. What do I do???

Relax. It’s fine. Just contact the admissions office in an email if it matters that much to you, but it is not likely to make a difference.

Fret not. Send them an update.
Then read this.
