SAT Score with Wrong Name

I am taking SAT subject test on Chinese this Saturday, which is two days apart. I have just realized yesterday that the name that I registered was NOT my legal name in my passport, but with my school name. I have called the Collegeboard, but they haven’t really answered my question, but just told me to change the date. Since I am taking the test at my school, the proctors say that they will let me take the test.

However, the problem is that I may not be able to use that score for applying colleges because the names do not match.

Even after taking the test, would I be able to change my name?
The College Board told me to send a scanned passport to them, but how do I send it to them through if I am living outside of America? Do I send them through e-mail account?
*If I send my scores with two different names, would the college not accept the scores?

Please I really need your help, please reply to me ASAP
