Hello Ramya!

You can know which questions are important in science by solving previous year question papers for science because most of times the weightage of the chapters, difficulty level of the question paper, pattern of paper, type of questions asked remain same.

So I will recommend you to check the previous year question papers for science from https://school.careers360.com/boards/kseeb/karnataka-sslc-science-question-paper-2025

You can solve and analyze the question papers smartly.

Thanks!
