# GATE 2022 Syllabus for Geomatics Engineering and Paper Combinations

Updated: Aug 31, 2021

GATE 2022 is going to see two new papers, Geomatics Engineering, Naval Architecture and Marine Engineering. The two new papers for GATE 2022 will be Naval Architecture and Marine Engineering (NM), Geomatics Engineering (GE). Here is the syllabus of GATE Geomatics. Adding these new papers(GATE Geomatics and GATE Naval Architecture), the total number of papers in GATE 2022 will be 29.

APSEd is launching a course on GATE Geomatics Engineering on 14th August!

In this blog, we will see three major things about the Geomatics paper.

Yesterday, on the 31st of July, IIT Kharagpur, the organising institute of GATE 2022 released the final notification for GATE 2022. GATE 2022 is going to start from 05th February 2022 and it has a four days schedule(Both Forenoon and Afternoon) - 05th, 06th, 12th and 13th of February 2022.

Here is the final notification.

## Syllabus of GATE Geomatics Engineering (GE)

Let us understand the various sections of the GATE GE paper.

Apart from the General Aptitude (GA) section that carries 15 marks, the question paper consists of two parts: Part A (55marks) and Part B (30 marks). Part A is compulsory for all the candidates.

Part B contains two sections: Section I and Section II. Candidates will have to attempt questions in Part A and questions in either Section I or Section II of Part B. The choice of Section I OR Section II of Part B can be made during the examination.

Part A consists of 36 questions carrying a total of 55 marks: 17 questions carrying 1-mark each (subtotal 17 marks) and 19 questions carrying 2-marks each (sub-total 38 marks). Some are MCQ type questions, while the remaining may be MSQ and/or NAT questions.

Either section of Part B (Section I or Section II) consists of 19 questions carrying a total of 30 marks: 8 questions carrying 1-mark each (sub-total 8 marks) and 11 questions carrying 2-marks each (subtotal 22 marks). Some are MCQ type questions, while the remaining may be MSQ and/or NAT questions.

Let us know it better with a flowchart!

The whole syllabus is quoted from the official notification.

For the Full Syllabus refer to the below-attached file. General Aptitude and Part A of the syllabus is mandatory for all. With these two, either section I or Section II of part B needs to be attempted.
