-Focus on keywords related to important topics in the science paper. Answers should include the correct keywords.
-Mind every scientific name, scientist's name, principles, and the results of scientists' experiments very carefully.
-Science primarily focuses on testing basic concepts in three areas: biology, chemistry, and physics. Therefore, when preparing for science, divide your time equally between all three subjects to gain a strong grasp of them.
-Note down all formulas, derivations, and chemical equations.
-Refer to NCERT textbooks to score well. All the questions will be based on the concepts given in the NCERT book.
