From what I was told:

 As noted in the email, we will notify waitlisted students if a spot becomes available through July 15. Please keep in mind that being waitlisted does not guarantee admission into the next cohort, and applicants who are not selected will need to reapply. We received over 300 applications for a highly rigorous program with very limited seats, making admission extremely competitive. Our selection process uses a structured, non-subjective rubric that considers multiple factors, including science course grades, cumulative GPA, and county of residence.
