CBSE Class 9 Science Syllabus 2017-18

Download latest cbse class 9 Science syllabus for the session 2017-2018. This year CBSE has changed the exam pattern. This year, there is no CCE pattern or division of syllabus for SA1 or SA2 as it used to be before. Your final exam will consist of 80 marks and 20 marks of internal assessment. This year complete syllabus will be there for your final/annual exam. Each year cbse keep on issuing revised syllabus. Although the topics and textbooks remain same, the contents within vary year by year. Along with Science syllabus for class 9 cbse has also issued the practicals work syllabus along with weightage of each chapter. That’s why it is strongly recommended to download new class 9 science syllabus 2017-18 this year and be on safe side.

Gone are the days of SA1& SA2, now you have to practise a lot in a more precise way covering complete syllabus! It’ll be better if you practise according to the Science syllabus. We’ve got several stories from students throughout the country regarding their poor performance in Science board exams. One noteworthy point was that most of them didn’t bother about the syllabus issued by CBSE, they just practised the sample papers or directly appeared in exams. It’s very important to avoid such situation. Syllabus acts as prima facie for your CBSE exam. It reduces the topics, tells the weightage of each chapter so that you can invest more time on important topics, tells the question paper format and much more.

Students are advised to download the class 9 cbse Science syllabus for the session 2017-2018 even if they have the previous year syllabus because there is a lot of changes in the syllabus, question pattern and weightage of each chapter.
