Ask a UC Davis student (for class of 2019)

I was admitted into UC Davis and then I committed to UC Davis and sent in my SIR. I had dropped a class(ap chemistry) after first semester during my senior year and I had notified the school as soon as it happened. I never heard back from them but then I got an email last week saying that my admission status is being reevaluating. Does anyone know how long it will take until I know whether or not I am still admitted? Will it be after May 1st because then I couldn’t commit to another school. Should I commit to Cal Poly Slo too just in case?
