__Exam Pattern of Civil Engineering for GATE Exam__

__Exam Pattern of Civil Engineering for GATE Exam__

Gate exam will be a Computer Based Test (CBT)

**Please note: Question Paper Structure, Marks distribution is common for CS, EE, ECE, ME, CSE, CH papers**

There will be total 65 Questions and the total marks of GATE Exam are 100.

The total duration of GATE Exam is 3 hours.

**Here is the division of the Marks:**

**General Aptitude (GA):** 10 questions of 15 Marks

**Engineering Mathematics:** 15 Marks

**Technical Questions** (subject of the paper): 70 Marks

**GATE 2016 Exam will contain two different types of questions:**

**Multiple Choice Questions (MCQ):**Objective questions carrying 1 or 2 marks, where each question will have a choice of four answers, out of which the candidate has to mark the correct answer(s), in all papers and sections.

**Numerical Answer Questions:**Each question of 1 or 2 marks in all papers and sections. For these questions the answer is a real number, to be entered by the candidate using the virtual keypad. No choices will be shown for this type of questions.

**The questions in a paper may be designed to test the following abilities:**

**Recall:** Questions will be based on facts, principles, formulae or laws of the discipline of the paper. Candidates are expected to be able to obtain the answer either from his/her memory of the subject or at most from a one-line computation.

**Comprehension:** These questions will test the candidate’s understanding of the basics of his/her field, by requiring him/her to draw simple conclusions from fundamental ideas.

**Application:** The candidate is expected to apply his/her knowledge either through computation or by logical reasoning.

**Analysis and synthesis:** In these questions, the candidate is presented with data, diagrams, images etc. that require analysis before a question can be answered. A synthesis question might require the candidate to compare two or more pieces of information.
