What do I need to transfer from CC to Stanford?

I have been doing research on transferring from cc to Stanford for a while and I have reviewed the previous discussion. However, I still have some questions.

First, let me start off introducing myself:

I am an international student from China and I am currently studying at CC in California. My major is math and economics because my initial plan was to transfer to UCLA and they have mathematical economics as a joint major.

GPA:3.93/4.0

Extracurricular:
-SI leader (SI is an academic assistance program and I am workinging as a math tutor for )
-School Track team (will join this Fall)
-PTK(honor society)

Volunteerism:
-Rescuing animals with a rescue organization
-Tutoring homeless kids

Secondly, my questions are:

1: How can I find out whether my coursework could be transferred to Stanford or not? I have checked with http://www.collegetransfer.net/Search/SearchforTransferProfiles/WillmyCreditsTransfer-Map/tabid/3380/Default.aspx?institutionId=2760. However, it turned out neither of my higher math course is transferable.

2: Is it mandatory to have SAT or ACT? If so, what grade do I need?

Lastly, I know the acceptance rate is very low; nevertheless, I believe there is no harm to try. Thank you so much in advance!

^ You can start out by reading some online articles on Stanford transfers:

My sense is that to be a successful Stanford transfer you need unique personal stories rather than stellar SAT/ACT and GPAs.

Thank you for your information, I will definitely read it!

Stanford grants general transfer units to each transfer. Once you are admitted and get on campus you walk around dept to dept with your old transcripts and they decide if they want to grant specific Stanford course credit on a class by class basis.

Per the most recent common data set (look at Section D2) Stanford accepted 1.4% of transfer students (2.234 applicants and 31 admitted). https://ucomm.stanford.edu/cds/pdf/stanford_cds_2017.pdf It isn’t worth spending time being concerned about what coursework might be accepted until you get in.

It is fine to shoot for the moon, but be sure to have a well thought out transfer application list that includes match and safety schools that appear affordable and that you would be happy to attend.
