# GATE CE Subject Wise Weightage – Important Topics and their weightage for GATE Civil Engineering exam

21 October, 2023 By Prateek Mishra, IMS, GATE Mentor

The Graduate Aptitude Test of Engineering (GATE) is a highly competitive exam conducted by 7 IITs and IISc to evaluate the technical reasoning of engineering graduates. So, if an engineering graduate is willing to appear in GATE for Civil Engineering, they are first supposed to analyse the complete syllabus. They need to be aware of the GATE CE subject wise weightage of all the important topics. This can be learnt by studying the frequency of the different types of questions being asked from various topics in the past GATE CE papers.

## GATE CE subject wise weightage

A list of the GATE CE subject wise weightage for all subjects is given below:

 Subject Weightage Category General Aptitude 15 Engineering Mathematics 12 Geotechnical Engineering 13 Group 1 (Mandatory) Environmental Engineering 11 Transportation Engineering 9 Fluid Mechanics 8 Strength of Materials 3 Structural Analysis 6 Group 2 Geomatics Engineering 6 R.C.C. 6 Irrigation and Hydrology 5 Steel Structures 3 Group 3 C.M.M. 2 Engineering Mechanics 1

To read more about the paper, its syllabus, and various topics, you can visit the official GATE 2024 website here – gate2024.iisc.ac.in

## GATE Civil Engineering preparation tips

After critically analysing the syllabus, the next step is to decide the sequence of reading the subjects.  All the technical subjects for Civil Engineering can be classified into three groups, namely Group-1 (Mandatory), Group-2 and Group-3.

Group 1 subjects are the primary subjects which build the foundation for subjects in Group 2 and Group 3. Hence, starting with these subjects is mandatory to understand all the concepts deeply. For example, the basics of the Strength of materials are required for efficiently reading Structural analysis, Reinforced Cement Concrete and Steel Structures. Likewise, the basics of Fluid Mechanics are needed for reading Hydrology, Irrigation and Open Channel Flow.

For General Aptitude, you can take any of the two methods: either study it along with the Group 1 subjects or keep 5 days reserved every month for finishing some chapters.

After finalising the sequence, an aspirant should have adequate and precise study material containing detailed explanations of the concepts and practice questions. IMS GATE Academy has one of the best study materials containing proper explanations of concepts, relevant theories, and strategic practice questions that cover all types of questions. Along with textbooks, exercise books, and other courseware, you also get access to a cache of videos, masterclasses, and seminars. The exercise books have clearly demarcated sections for each subject, with questions well-placed within the different chapters. Questions for every chapter are categorised as Levels 1, 2, and 3 based on their difficulty level, allowing you to build your skills up slowly.

## GATE CE subject wise weightage – Important topics for each chapter

Based on the frequency of questions asked in the GATE, some critical areas require more focus and revision. For your reference, here is the list of all such essential topics subject-wise for different chapters for all the subjects of Civil Engineering.
