Here are some mathematics resources that may be helpful!
Directed Reading Program | Each semester, students have the opportunity to work with a graduate student mentor to study a math-related topic at an individual pace and then present a summary at the end of the semester.
JHMT | In the past, JHU has hosted a local math competition (Johns Hopkins Math Tournament) designed to challenge and excite local high school students. This competition, designed to mimic the American Mathematics Competitions (AMC) series and American Regions Mathematics League (ARML), has been student-led for the past two decades.
Putnam Exam | An annual exam for undergraduates held the first Saturday of every December. Considered the most prestigious university mathematics competition in the world, Hopkins competes annually.
REU | REU programs are one of the best ways for undergraduate math students to prepare for work in mathematics and for exploration of the possible research fields. These programs are held in the summer at various universities around the country. They are funded by the National Science Foundation. You are housed and fed, and paid while you work on a research problem and potentially attend seminars. For a complete REU list visit the NSF website. Applications typically require 2 letters of recommendation, transcript and perhaps an essay and are usually due in February or March.
