# MOST IMPORTANT TOPICS FOR CSIR-NET/JRF AND GATE : PHYSICS or Physical Sciences

Exams are not about only the knowledge of your Subject but also about your strategy of preparing and performing in the exam. Competitive exams are a means to compete with others and cross the cut off with better planning. Finding the important topics from the whole syllabus and practice them is also a part of the strategy of preparing for competitive exams.
