Rescinded for dropping a class?

I signed up for Advanced Topics in Mathematics and reported that I would take that course during my senior year, but I dropped it within the first few days. Because I completed my CSU application so early, I forgot that I still had that class listed on the application and failed to notify Cal Poly SLO before they accepted me. I also was unable to list that I was taking AP Chemistry because I included too many science classes. I sent an email today explaining that I switched Advanced Topics for AP Chemistry.

Can my acceptance be rescinded because I did not notify them in time? I already took math up to Calculus 3 and Linear Algebra and completed all requirements if that matters.

99% probably not but why remain insecure? Call them.

Call/email and ask. Try to get their answer in writing (rather than phone). Don’t guess.
