Ans. The Unified Council has framed NSTSE to find promising minds in the field of Science. Thus, NSTSE will seem very difficult for students whose concepts are not clear. Whereas to students who have a clear conceptual understanding of Science and Mathematics, it will be easier. No test is difficult if the candidates are well prepared. The bar of difficulty is a little higher than that of school examinations. Hence, it is advised by the Council to solve sample papers and take NSTSE mock tests. This way, candidates can get more familiar with the test and can readily answer the questions in the actual exam.
