I.C.S.E. is one of the most famous non-governmental Board of Education serving quality education across country. Biology is one of most easiest subject to prepare for the exam as it require a little attention to earn good marks. The main purpose of setting the given Biology Sample Papers for Class 10 ICSE is to make students aware about the type of questions asked in the exam as per latest pattern.
Tips for Preparations:
(1) There will be one theory paper of two and half half hour containing 80 marks and the remaining 20 marks will be evaluate on the basis of Internal assistance. Thus to prepare for theory exam is very important.
(2) Section-I consists of 5 marks questions which are of short answer type. So, answer them in to-the-point manner.
(3) Section-II consists of long answer questions including diagrams. So, prepare them as per the format carefully.
(4) Solve sample papers as much as possible to maintain your Time Management during the exam.
