Course Change

I was recently admitted ED to JHU.

I had a level change from AP Calc to Business Calc G/T at the beginning of second quarter (before decisions came out). Both courses are weighted the same within the school system since they have the same content and I still plan to take the AP exam in May.

I had contacted the admissions office asking whether I had permission to change class and it was granted, but they told me to have my guidance counselor sent an email to them once the change is made. But, my counselor just told me that they have forgotten to send that email. Will I get rescinded for this and what should I do now?
