PYQ Mock: IIT JAM 2026 Biotechnology (BT) Section A

IIT JAM 2026 Biotechnology (BT): the 30 single-answer questions of Section A from the official paper, shown as pictures of the original questions. Choose A, B, C or D as printed in the picture. Q.1 to Q.10 carry 1 mark and Q.11 to Q.30 carry 2 marks, so the maximum here is 50. A wrong answer costs one third of the question's marks (shown as -0.33 and -0.67); an unanswered question scores zero. The multiple-select and numerical-answer questions of Sections B and C cannot be answered in this exam room and are not included. 90 minutes is the practice time; the real paper has 60 questions in 3 hours. Answers follow the official answer key published by the organising institute (https://jam2026.iitb.ac.in/files/BT_AK.pdf). Original paper: https://jam2026.iitb.ac.in/files/BT_QP.pdf.
