ISC Biotechnology Specimen Paper 2023 for Class 12: The Council for the Indian School Certificate Examinations (CISCE) has released the specimen papers for the annual higher secondary ISC Class 12 exams. The 2023 ISC exams are here, and the next paper is of Biotechnology (Code: 878) theory. The subject is a favourite of medical-science students and involves the use of biology for technological advancement. As such, biotechnology is heavy on theory and calculations. Considerable practice is required to succeed in the ISC Class 12th Biotechnology exam, and there’s probably no better way to achieve that than by solving specimen papers. It also gives students an idea of the biotechnology paper pattern and the level of difficulty to expect in the final exam. Solving sample papers also reduces exam fears, especially for lesser-opted and tough subjects like biotechnology. Check here and download the ISC Biotechnology Specimen Paper Class 12 PDF.
