Change grades and alternate major

I am an applicant for UC Davis Fall 2018 semester. I updated my coursework to include my second term grades. Was it too late to update my coursework? Will they re-evaluate my application if they have reached a decision? Also, I typed in the additional comments section of the coursework update that I would like to request to change my alternate major to environmental chemistry. Will they grant that request?

You are a Freshman applicant or Transfer?

UC’s do not consider your Senior grades in admission decisions unless they specifically ask for them in a supplemental review. UCD also rarely considers alternate majors so you could email admissions if it is even possible to change it at this point and along with inquiring if the grade update will have any impact.
