Should I study from NCERT books for RRB NTPC CBT 2 advanced mathematics?

NCERT Class 9-10 mathematics textbooks provide the perfect foundation for RRB NTPC CBT 2 advanced topics. Cover chapters on algebra, trigonometry, geometry, and mensuration thoroughly. However, supplement NCERT with RRB-specific practice papers since exam questions test application skills beyond textbook problems. Solve NCERT examples and exercises first, then move to previous year CBT 2 papers for exam-pattern familiarity.

How much time should I dedicate to each advanced mathematics topic?

Allocate preparation time based on weightage: algebra (35-40%), geometry (25-30%), trigonometry (20-25%), mensuration (15-20%), and number system (10-15%). If you have 3 months for CBT 2 preparation, spend 5-6 weeks on algebra and geometry combined, 3 weeks on trigonometry, 2 weeks on mensuration, and 1 week on number system revision. Adjust based on your current strength and weakness in each area.

Are calculators allowed in RRB NTPC CBT 2 for solving advanced mathematics problems?

No, calculators are strictly prohibited in RRB NTPC CBT 2. You must solve all advanced mathematics calculations manually or using rough paper provided at the exam center. This makes speed calculation practice essential—memorize squares up to 30, cubes up to 20, and common fraction-decimal conversions. Practice mental math techniques and Vedic mathematics shortcuts to improve calculation speed under exam time constraints.

Conclusion: Your Next Step

RRB NTPC CBT 2 advanced mathematics topics require strategic preparation focused on algebra, geometry, and trigonometry. These three sections contribute 60-70 marks and determine your final selection. Master fundamental concepts from NCERT Class 9-10 before attempting RRB-level application problems.

Prioritize practice over passive reading—solving 1000+ problems across all topics builds the speed and accuracy needed for CBT 2's competitive environment. Track your topic-wise performance through sectional tests and strengthen weak areas systematically.
