Advising Hold

I’m a freshman that is planning on switching majors. Somehow, I missed the email the CSC department sent about filling forms for pre-registration advising around spring break, and only just filled it today. I have since emailed advisors at both the CSC and Chem E department (the department I am switching into) but my enrollment date is Monday (4/6) and I only got all this done today (4/1). What are the chances of my hold still being removed on time? What else can I do?
