The passing marks for the students of Class 8 ICSE are 45. But students must only aim to get higher because this is the easiest grade and the right stage to enhance their knowledge. To secure good marks students have to keep practising with all the sources possible and there are no negative markings in Grade 8. Still every mark counts. So students should be careful while answering the questions and  try not to make any mistakes by answering questions that they are not absolutely sure about.
