You must first follow the path for transfer students, and from there, you will be able to see questions that will categorize you as a 3/2 applicant. The deadline for submission of the 3/2 application is April 1. Admission to the program is determined by the Caltech Upperclass Admissions Committee.

  • Complete one year of physics (two years recommended).
  • Complete one year of mathematics (including multivariable calculus and differential equations; two years recommended).
