GATE Civil Engineering Subjectwise Weightage – Important Topics and Their Weightage for GATE CE exam
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 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 Group1 (Mandatory), Group2 and Group3.
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 wellplaced 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.
