FAQs

Q.1 Which section carries the highest weightage for the Grade III Technician exam, and what should be my main focus?

The General Science section typically carries the highest weightage (around 40 questions). Your main focus should be on NCERT/SCERT Physics and Biology up to Class 10, concentrating on fundamental concepts, formulas (Work, Power, Electricity), and human physiological systems (Circulation, Digestion).

Q.2 Are the questions on Mathematics calculation-intensive, and what topics frequently repeat?

Yes, the Mathematics questions primarily test speed and accurate calculation. Highly repeated topics include Time & Work, Time, Speed & Distance (especially train problems), Simple & Compound Interest (SI/CI), and basic mensuration formulas for 2D/3D shapes. Mastering the BODMAS rule for simplification is also crucial.

Q.3 For General Awareness, should I focus more on Current Affairs or Static GK?

You should balance both, but Static GK based on the repeated patterns (Polity: Fundamental Rights/Duties, History: Freedom Struggle events/dates, Geography: Rivers, Planets) is highly stable and repeatable. Limit Current Affairs preparation to major national awards, government schemes, and key science/defense technological developments from the last 6-9 months.

Q.4 What is the most effective way to practice the Reasoning section to maximize my score?

Reasoning is about recognizing patterns. The most effective way is to practice daily by solving questions from the most frequent types: Number/Alphabet Series, Coding-Decoding, Syllogisms (using Venn Diagrams), and Direction Sense. Time yourself while practicing to build speed, as these questions are generally less time-consuming once the pattern is identified.

Q.5 Is there negative marking in the RRB Technician CBT, and how should this influence my attempt strategy?

Yes, there is a negative marking of 1/3rd of the marks allotted for every incorrect answer. This should lead you to adopt a strategy where you prioritize accuracy over sheer attempts. Only attempt questions you are reasonably confident about, especially in the General Science and Mathematics sections, to avoid unnecessary deductions.
