TN Quarterly Exam Time Table for Class 10 to 12 (2025–26): Chapters, Syllabus & PDF

Quarterly exams are an important part of the academic year for students in Tamil Nadu. They not only test what students have learned in the first few months but also prepare them for the half-yearly and annual examinations.
For the academic year 2025–26, the Tamil Nadu School Education Department has officially released the Quarterly Exam Timetable for Classes 10, 11, and 12.
Student of SSLC (Class 10), Plus One (Class 11), or Plus Two (Class 12), this guide will help you with complete details.
Quarterly exams act as a checkpoint in the academic year. Instead of rushing into half-yearly exams, students get a chance to revise the first set of chapters thoroughly.
For board exam students of Class 10 and 12, these exams are especially important because they help in building a strong foundation and time management skills for the final board exams.
The Tamil Nadu Class 10 (SSLC) quarterly exams will be held from September 15 to September 26, 2025. The exams are conducted in the morning session.
