Caltech is need-sensitive in admissions for international students, and this form affirms whether you will apply for financial aid. As an international student, if you plan to apply for financial aid at any time during your undergraduate career here, you must apply for it at the time that you apply for admission. Even if you do not plan to apply for aid, you must complete the form. Please note: International freshman candidates may apply Early Action only if they are not applying for financial aid. International freshman candidates seeking financial assistance must apply Regular Decision.We accept applications from students who have completed the approved curriculum provided by their home countries. These include, but are not limited to, the IGCSE, O, AS, and A Level curriculums; Cambridge Pre-U, AP, IB, and local public options may be considered as satisfying high-school course requirements. The most competitive international applicants whose schools offer the IGSCE curriculums usually present three A Level exams (the physics exam is required) with grades of at least an A or B. Competitive applicants whose schools offer the IB curriculum will have scores of 6 or 7 on their IB exams, including their "predicted" grades.
