@Rivet2000 : Everybody knows all Stanford students are admitted as undeclared. The School’d like to to make a balance even though students choose their major in junior year. When you search the CC Stanford thread, you can see some comments regarding this issue.

There are some students who saw their admission files and posted here. Students mentioned the notes they had seen on thier admission files.
