Why in news: In Dr B.C. Roy Engineering College v State of West Bengal (2026), the SC held that fees for an entire professional course must be notified before admission.

For Mains: Use for GS2 questions on education governance and private-sector regulation; the 'certainty principle' frames fee notification as protection for students and families.
