The Telangana State Board of Intermediate Education (TSBIE) will publish the TS Intermediate Biology Syllabus for the latest academic session 2025. Students can access the Telangana Board 12th Biology syllabus 2024 at tsbie.cgg.gov.in. The TS inter 2nd year Biology subject is divided into two parts, i.e. Zoology and Botany. There are 8 units in Zoology and 6 units in Botany, which are further divided into various chapters. In addition, there will be practical examinations for Botany and Zoology separately. In the TS Intermediate Botany syllabus 2025, Chapter 5, Morphology of Flowering Plants is the highest weightage carrying chapter which will carry 22 marks. While the maximum weightage carrying chapter in Zoology is Chapter 10, Genetics with 18 marks. Students must go through the TS Intermediate Exam Pattern 2025 for Biology before starting with the preparation.
Both TS Intermediate Botany and Zoology theory exams will be conducted for a total of 60 marks. The remaining 40 marks will be allotted for the practical exams. The practical and theory exams for both will be conducted on separate days. To prepare for the board exams, students can check the syllabus available in PDF format. TSBIE will release the TS Intermediate time table 2025 in December 2024 tentatively. The Telangana inter exams are expected to be conducted in February-March 2025. The practical examinations are to be held in February 2025. Read the article carefully to get the detailed syllabus. Through the syllabus, students can plan to prepare the chapters and achieve daily targets that help them to improve their performance in the board exam.
