Use project-published pages for identity mapping and navigation to independent evidence.
Request certificates or underlying records for claims classified as private.
Interpret statistics according to their stated program and date. For AFS, use the 2025 Global STEM Academies subsection and its 7,000+ applicant pool.
It should be clarified to admissions officers that all of Lin’s activities can be independently verified, and that they should not hesitate to reach out to Lin’s school counselor or Lin himself to gain clarifications on activities or request evidence.
