GATE 2025 GEOMATICS ENGINEERING PATTERN
ONLINE TEST
GATE 2023 Geomatics Engineering (GE) Exam Pattern has been released on the official website. As per GATE 2023 Geomatics Engineering (GE) Exam Pattern, the question paper is divided into three sections- General Aptitude, Part A and Part B. Students have to compulsorily attempt Part A while out of Part B, they can attempt any one section out of two: Section I and Section II.
GATE Geomatics Engineering (GE) is a new paper introduced by IIT Kharagpur in 2022. This paper basically checks the aspirants’ geomatics skills. Geomatics is a specialised field of study. It entails gathering and analysing geospatial data and processes of land, oceans, natural and manmade infrastructures, as well as measuring, creating, constructing, and operating systems for doing so. In order to accomplish so, geomatics professionals use the most up-to-date satellite, laser, acoustic, and information technology.
The General Aptitude section is common for all the GATE exam and has 10 questions devoted to this section. This section is of total 15 marks thus constituting 15% weightage of the total weightage of paper. Geomatics Engineering Part A (compulsory) has 36 questions and is of total 55 marks, thus constituting 55% weightage of the total weightage of paper. Similarly, Part B (Section I or Section II) has 19 questions and is of total 30 marks, thus constituting 30% weightage of the total weightage of paper. Check GATE Geomatics Engineering Syllabus

Ans. Many GATE toppers leave PSU and join NITIE, instead of IITs because it offers better placements. Usually, students with good scores join ONGC, NTPC, BHEL, IOCL, and others. Despite the good salary, PSU jobs can get monotonous after a few years. So, the top rankers start looking for better career options. If they wish to do an MBA, they need to prepare for CAT. Some do prepare for CAT, but many join NITIE as it is an easier option. NITIE takes admission through GATE and the GATE score is valid for 3 years. So, they can easily get admission based on their GATE score. Also, the institute has a great placement record. During the NITIE Mumbai placement in 2022, the average CTC offered was INR 25.41 LPA. The video below will convince you further to join NITIE Mumbai Overall, its the excellent opportunities offered by NITIE that makes mant GATE toppers leave PSU and join NITIE Read more
Ans. Here are some strategies that can help you prepare for GATE and ESE simultaneously. Compare the syllabus of GATE and ESE. Go through the previous years' questions of both. The technical portion of both examinations overlaps a lot. The major difference is question patterns and styles. Different types of questions are asked on the same topics. GATE tests aptitude for solving technical questions. While ESE puts more emphasis on technical details. Figure out which subjects contribute more to which examinations. If you have less time, start with GATE preparation. The topics can be covered easily and in less time. Once you are through GATE preparation, you can solve ESE questions without much difficulty. Focus on GATE and ESE preparations only. First, go through the syllabus thoroughly. Once you are done with the syllabus, go through your notes and solve previous years' questions. Solve test series, and review hard questions. Analyze the tests you give and work on your mistakes. Read more
Ans. GATE consists mostly of numerical questions. It tests the aptitude for solving questions in less time. BITS HD papers have 10-15 numerical questions usually. The numerical questions aren’t on the same level as GATE and are just formula-based problems. Usually, around 80-90% of BITS HD questions are theory oriented. You need to have a good grasp of your engineering subjects to score well in BITS HD. The questions can come from anywhere in the syllabus. BITS HD usually consists - 15 Mathematics questions (difficulty usually higher than GATE) 15 general English questions 70 Engineering discipline questions Also, note that BITS take admission based on GATE scores as well.

Ans. The required GATE rank depends upon various parameters like The engineering branch Company (PSU) Number of vacancies for the stream People who are graduating in 3-4 years are lucky as both IOCL and ONGC are planning to recruit in bulk because of massive retirements in both the companies. The mechanical and chemical branches are expected to have the most vacancies. Candidates will be called in a 1:5 ratio and thus, interviews will be the major determining factor of your selection. If you are unable to showcase your knowledge and talent during the interview, even a single-digit rank cannot guarantee your admission. A minimum of 40% marks are required to pass the interview. So if you get a call for the interview, donât let your rank discourage you or even make you overconfident. Read more
