For high school students aiming to attend a top college, July is filled with exam prep, community service, lab work, internships, music and athletic camps. With Stanford taking only 5.1 percent of applicants and Yale just 7.1 percent, the odds are so uncertain that no effort is spared to build a competitive profile.

Applying to college is an anxiety-filled rite-of-passage for students and parents alike. For Asian-American families, however, the anxiety is mixed with dread. They know that their race will be used against them in admissions, and there is nothing they can do but over prepare.

I experienced this when I applied last year. I grew up in a Chinese-American family in Union City, where my parents are educators and encouraged me to pursue my interests broadly. I sing and play the piano. My choir performed at the San Francisco Opera and President Obama’s first inauguration.

I founded the math club at my high school, James Logan, and debated in tournaments throughout the West Coast. I took the most challenging classes in school and graduated in the top 0.5 percent of my class. I got a perfect 36 on the ACT and 2230 on the SAT. I wanted to study international relations and become an ambassador.

I was rejected by Yale, Princeton and Stanford.

My disappointment turned into anger when I learned that Asian-Americans are being held to higher admissions standards by the selective schools. We have been the fastest growing minority group in America, and yet our presence on some Ivy League campuses has declined in the last 20 years.

A 2009 study found that Asian-Americans were admitted at the lowest rate of any racial group. For Asian-American applicants to have an equal chance of getting into an elite private college, we had to score 140 points higher than whites on the SATs, 270 points higher than Latinos and 310 points higher than blacks.

Here in California, Asian-Americans constitute 19 percent of Stanford’s undergraduates compared to 39 percent at UC Berkeley and 45 percent at UC San Diego. The disparity exists because of the law. In 1996, California voters adopted Proposition 209, which banned racial preferences in public education.

In 2003, the U.S. Supreme Court ruled that schools like Stanford that are not subject to Proposition 209 may give minority applicants a “race plus-factor” to boost their chances of getting in. The High Court acknowledged that the practice deviates from the equal protection of the laws but is permissible for 25 years to enhance campus diversity.

Though a majority of Asian-Americans opposed Proposition 209, many now appreciate the fairness of race-blindness. We have been driven to this understanding because the race-plus factor, which is supposed to help increase black, Latino and Native American enrollment, is being used as a minus-factor against us.

Whatever unequal treatment we may encounter elsewhere, we felt assured that the UC schools will not disadvantage us — that is, until this January, when the State Senate passed Senate Constitutional Amendment No. 5 (SCA-5).

The bill proposed to repeal Proposition 209 and allow the UC schools to use racial preferences. Our community reacted with fury at the Asian-American senators who supported SCA-5 and forced them to have the measure tabled.

The reaction surprised many but not families like mine and countless others whose grievances have been building for years.

Last June, I filed complaints against Yale, Princeton and Stanford with the U.S. Department of Education. This April, the Supreme Court upheld voter initiatives that ban racial preferences. I hope I have a chance to present my case.
