Princeton的iBT要求：（http://gradschool.princeton.edu/admission/applicants/guide/required/}

TOEFL is a test developed by the Educational Testing Service. A minimum cumulative score of 250 on the computer-based version of the test, 600 on the paper-based version, or 71 on the web-based version is required by the Graduate School, and departments often set a higher standard.

Bekerley的iBT要求：（http://www.grad.berkeley.edu/admissions/admis_require.shtml）

For purposes of admission, your most recent score must be at least 570 for the paper-and-pencil test or at least 230 for the computer-based test, or at least 68 for the Internet-based test (iBT). Please contact individual academic departments for more information, as they may choose to require a higher score.

真的有人用不到100，甚至不到90的iBT分数来申请这些学校吗？
似乎看到过台湾学生的总结，用80多分的iBT申请到Carnegie Mellon University的理工专业。
是不是对于理工学科，iBT过线后，分数差异的影响就很小了呢？
