What are the common mistakes that should be avoided?
There are certain mistakes, such as skipping unit conversions, using a calculator, and more, that should be avoided by the candidates. Some of these are given below:
- Skipping unit conversions (km/h to m/s).
- Misreading “successive” vs “simultaneous” percentages.
- Neglecting to rationalise surds or simplify fractions wastes time.
- Using calculator habits in mock tests; practice without a calculator where possible (paper-based exam mindset).
What is the appropriate time management strategy for RRB NTPC Exam?
The appropriate time management strategy is to divide every important mathematics topic according to its weightage. Check out the details:
- First 10–12 minutes: solve all very easy arithmetic and number system questions (easy marks).
- Next 20–25 minutes: take on time/speed, work/time, and straightforward algebra.
- Last 15–20 minutes: tackle mensuration, geometry and trickier algebra.
- If a question looks messy or long, mark it and move on – come back only if time permits.
Where can I get a revision plan for Mathematics?
Applicants can get a revision plan for mathematics in this article. Check out day wise plan below:
- Days 1–7: Master formulas and do topic-wise short quizzes (20 Qs/day).
- Days 8–16: Take timed mock tests; review mistakes thoroughly.
- Days 17–24: Focus on weak topics; do mixed topic sets under timed conditions.
- Days 25–30: Light revision: formula sheet, 2 full mocks, and relax the day before the test.
