The CBSE Class 10 Mathematics half-yearly (mid-term) exams for the 2025-26 academic session were conducted by affiliated schools between September 15 and September 30, 2025. These exams are structured around an 80-mark theory paper and a 20-mark internal assessment, covering the first half of the NCERT syllabus, including key units like Algebra, Geometry, and Trigonometry. While schools typically provide results in October, students can use the question papers and answer keys to calculate their probable scores and identify areas needing improvement before the final 2026 board exams.
