BTSC Work Inspector Syllabus Topic wise Weightage 2025
Thus, a tentative weightage could be:
| Section | Approx No. of Questions | Approx Marks | Approx Weightage (%) |
|---|---|---|---|
| Technical / Civil Engineering | ~ 50–60 | ~ 50–60 | ~ 50–60 % |
| General Awareness & Current Affairs | ~ 20–25 | ~ 20–25 | ~ 20–25 % |
| Reasoning & Numerical / Aptitude | ~ 15–25 | ~ 15–25 | ~ 15–25 % |
Note: Some sources suggest ~ 50 in General Awareness & ~ 50 in Technical (so 50:50 split) but that seems less common.
Best Books to Cover BTSC Work Inspector Syllabus
Here are some of the best books (and resources) you can use:
| Subject | Recommended Book(s) | Why / What it Helps With |
|---|---|---|
| Civil Engineering / Technical | “Civil Engineering Through Objective Type Questions” by S.P. Gupta & R.S. Khurmi | Good for objective questions format, covers many basic topics |
| SSC JE Civil Guide (by Disha Publications or similar) | Because the JE exam syllabus overlaps a lot with what you’ll need for technical part for Work Inspector | |
| Standard Diploma / Degree level civil engineering textbooks (for deeper understanding) | To build conceptual clarity in structural analysis, hydraulics, materials, etc. | |
| Indian Standard Codes (IS Codes relevant to civil works) | When questions ask about specifications or code-based requirements | |
| Reasoning / Aptitude | R.S. Aggarwal — Quantitative Aptitude | Very popular and covers a wide range of arithmetic & number theory topics |
| Arihant / Kiran / RS Agarwal reasoning books | For logical reasoning, verbal / non-verbal aptitude etc. | |
| General Awareness / GK | Lucent’s General Knowledge | Good for static GK, Indian polity, geography etc. |
| Bihar GK by Dr. Manish Ranjan (or other state-specific GK books)* | Since this is a state-level post, knowing Bihar-specific facts will help | |
| Monthly magazines / current affairs compilations (e.g. Pratiyogita Darpan, Competition Success Review) | To stay updated with recent events, schemes, developments | |
| Practice / Mock / Previous Year Papers | Collection of solved papers for SSC JE / state civil works exams | Helps you get used to the exam pattern, time management, and question styles |
| Model / mock test books (from publishers like Kiran, Arihant, etc.) | For timed practice under exam conditions |
Strategy: How to Use These Books Effectively
-
Start with fundamentals first
Use standard textbooks (from diploma or degree level) to fully understand each technical topic (like surveying, structural, hydraulics). Once your concepts are clear, move into the objective / MCQ books to practice. -
Parallel GK + Current Affairs
Don’t leave GK till the end. Read daily or weekly current affairs and revise state (Bihar) GK regularly. -
Integrated practice
After finishing a topic in technical, immediately solve objective questions from the MCQ / guide books. Then, after covering a few topics, take mini mock tests mixing technical + aptitude + GK. -
Use previous year / analogous exam papers
Since “Work Inspector” is a state technical post, prior SSC JE papers, civil works inspection papers, or similar state-level technical exams will be close in style. This helps in understanding difficulty levels, topic weightage, and time management. -
Revision and formula sheets
Maintain a sheet of important formulas, codes, conversions, etc. Revise weekly. -
Focus on weak areas
As you practice, identify weak topics (say, surveying, or some part of structural design) and allocate extra time to reinforce them using the textbook + problem practice.
