Answer: The syllabus and integration of chapters in the NSTSE 2021 exam increase as the classes ascend. But the marks allotment for every question remains the same. One question from a 3rd standard’s paper and that of a 12th standard’s paper carries the same marks.
Each question in NSTSE carries 1 mark irrespective of subject and standard. The Critical Thinking section is of 5 marks, for every class. The Mathematics section carries 25 marks, except for classes 11-12 PCB where Biology carries 25 marks. Science section, in general, is of 30 marks, in the case of PCM and PCB, Physics and Chemistry carry 15 marks each.
