Paper 2:

SyllabusReference BooksStrategy & Analysis
Construction, Construction Technology & CPMBuilding Construction by Arora & Bindra, CPM by UK SrivastavaQuestions are diverse & mostly predictable. Refer previous years’ IFoS & CSE papers & study accordingly. Prepare your own notes & it’ll help you revise faster. Questions from Engineering Economics are popping out of nowhere. UK Srivastava has covered it beautifully. Also I feel in this humongous theoretical section, one should study with photographic memory. Memorize diagrams & not data. Let the answers flow from your perfect diagrams.
SurveyingBC Punmia (Laxmi Publications)Please do Photogrammetry without fail. If you want to skip this topic you can, but do photogrammetry without fail. Remember basic things here like levelling & PT survey
Railway EngineeringSaxena & Arora (Dhanpat Rai publications)I did most of this part from NPTEL videos however I’d recommend NPTEL videos only for ‘Points & Crossings’ part of Rail Engineering. Questions are mostly simple & attemptable. However be ready for bouncers like 2014 CE questions.
Highway EngineeringJusto Khanna & NPTEL softcopies of same course.Since syllabus is huge, don’t spend much time on any particular section. Solve numericals from Justo Khanna. Do signal designs well.
HydrologySK Garg (Primary source), Ven-Te-Chow (optional)Over the years, direct questions on UH, no. of rainfall gauges have reduced. Focus is more on complicated topics as far as numerical are concerned.

However theory questions are much on the lines & predictable

Irrigation EngineeringSK GargSyllabus is crisp & previous years’ questions can help immensely. Do theory well
Environmental EngineeringSK GargThis topic I feel needs most number of revision. There are less formulae so do them well. UPSC has knack of asking unconventional formulae from this topic (Eg. 2013 CE question on plume).
Make notes & revise them multiple times

Strictly follow the syllabus

Keep an eye on previous years’ papers.

Questions these days are a step ahead of what we generally study. I mean you’ll find questions in exam from mostly skipped topics.

 

Strategy

Merits

  • Engineering subject so with thorough  preparation you can score very good marks in this, no such surety for humanities topics like pub ad, pol sci, etc.
  • Allows you to appear in Engineering services exam, GATE (for PSU jobs), pursue further studies – lots of back up options remain available
  • You can even try the Engineering Services exam if you prepare for civil engineering.
  • Only civil engineering background in their graduation can opt for this subject.optional recommended only for civil engineers.

Demerits

  • The syllabus is vast.
  • It would be very difficult to actually cover the whole syllabus.
  • There is no overlap with general studies in this subject.
  • UPSC can ask dynamic questions and these can be difficult to answer unless you have a deep knowledge of the subject.
  • There will be score equalisation done to make it at par with art subject scores. I.e if you have solved a 10 marks question upto perfection, then at max 6 or 7 marks shall be given which is the case in social subjects.

How to prepare:

  • Memorise the Syllabus.
  • Stick to limited reference books
  • Before starting preparation, go through previous year qps
  • One should know the basic concept of Civil engineering to tackle Paper II.
  • Prepare basic concepts first ,make notes related to that.
  • Make short notes, flowchart and diagram while  preparing. These short notes will help in revision time.
  • Updates regarding  the up-to-date data taken from Government reports annual report regarding Civil Engineering.
  • There would be plenty of diagrams for you to score.
  • The essential part of UPSC IAS Exam preparation is solving at least 10 of the previous year UPSC Mains questions papers.
