Can I apply for a Master's degree at UPD as an incoming graduate?

Hi, I am an incoming graduate this year, and I would like to apply for an MS in Applied Maths. I am worried about the admission process, given that I won't be able to provide a true copy of my grades until May T-T. I also don't know where to submit my application; the College of Science's website is a little difficult to navigate. I also checked if it is within the department I want to apply to, but it is not there. Any information about the process would be very helpful. THANK YOU SMM
