IISER Admissions · 2026 brochure and round-wise closing ranks · Exam cycle 2026 · Checked 2026-09-28
The brochure says not every IAT candidate receives a rank and a rank does not guarantee admission. The official 2026 admissions portal provides round-wise institute/programme closing ranks. Those tables have not yet been transcribed here; there is no single admission cut-off for all IISER programmes.
