Sample Paper Class 9 – Science

Science is a really broad and complex subject. It consists of laws, equations, diagrams etc. In Science, every concept or a law is connected to another. So, you cannot afford to make a mistake or skip something. Understanding science would require you to test your knowledge from time to time. NTSEGuru experts have composed detailed and effective sample papers. Solve as many as sample papers possibleto get an insight of your strengths and weaknesses.

Here’s a bonus sample paper for you to practice from.
