Civil Engineering Objective Type and Conventional Questions and Answer

By //

Civil Engineering Objective Type and Conventional 

Questions and Answer 


For civil engineering students who are aspiring for a central government job, the book can be quite helpful for preparation of applicable competitive exams. The thoroughly revised and edited version is compiled for better understanding of suitable candidates. The book features various practice questions and previous years’ examination questions, so the reader could get clear idea about upcoming exam pattern.

The book has been divided into different sections that include numerous multiple choice questions, typical questions that are generally asked by U.P.S.C. for Civil engineering and GATE. Furthermore, the book also contains synopses, conventional and important/typical numerical questions on various topics from some key competitive examinations.

A small section containing short questions and answers has also been included in the book. This section includes nearly 12 major topics in Civil Engineering. This is a useful guide for candidates who are already clear about important engineering concepts, but want to self-evaluate their performance based on scoring.
