GATEFluid Mechanics (XEB Engineering Sciences) Exam Pattern
Exam Pattern
Graduate Aptitude Test in Engineering (GATE) Fluid Mechanics (XEB Engineering Sciences) has 3 hours duration.

The question paper will consist of both Multiple choice questions (MCQ) and Numerical answer type (NAT) questions.

In all the papers, there will be a total of 65 questions carrying 100 marks, out of which 10 questions carrying a total of 15 marks will be on General Aptitude (GA).
GATE Fluid Mechanics (XEB Engineering Sciences) would contain questions of two different types in various papers:
(i) Multiple Choice Questions (MCQ) carrying 1 or 2 marks each in all papers and sections. These questions are objective in nature, and each will have a choice of four answers, out of which the candidate has to mark the correct answer(s).
(ii) Numerical Answer Questions of 1 or 2 marks each 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 answer can be a number such as 10 (an integer only).
General Aptitude (GA) Questions
In all papers, GA questions carry a total of 15 marks. The GA section includes 5 questions carrying 1mark each (subtotal 5 marks) and 5 questions carrying 2marks each (subtotal 10 marks).
A candidate appearing in the XE paper has to answer the following
1. Section A – Engineering Mathematics
2. GA – General Aptitude
3. Any two of XE sections B to H
XE paper
The choice of two sections from B to H can be made during the examination after viewing the questions. Only two optional sections can be answered at a time. A candidate wishing to change midway of the examination to another optional section must first choose to deselect one of the previously chosen optional sections (B to H).

XE Paper
In XE paper, Engineering Mathematics section (Section A) is compulsory. This section contains 11 questions carrying a total of 15 marks: 7 questions carrying 1mark each (subtotal 7 marks), and 4 questions carrying 2marks each (subtotal 8 marks). Some questions may be of numerical answer type questions. Each of the other sections of the XE paper (Sections B through H) contains 22 questions carrying a total of 35 marks: 9 questions carrying 1mark each (subtotal 9 marks) and 13 questions carrying 2marks each (subtotal 26 marks). Some questions may be of numerical answer type.

How to prepare
Preparation Strategy
Make a proper Time Table
It is very important that you make a time table and stick to it and you will have an exact idea of what you are required to study and the time required for it.
Concept clarity rather than rote learning
It is essential that you have a clear idea of the formulas and concepts rather than rote learning of things for the papers. While you might require it for memorizing formulas it is important that for other stuff you make sure you clear your basis and concepts before moving on.
Prepare Notes
It is very important make small notes or a comprehensive list of formulas on each covered topic and chapter which will come in handy at the time of revision. This will require you to be regular with your work but will surely make things easy at the time of revision.
Seek guidance
It is not possible for you to know everything in your syllabus, at least not at the time of preparation. Sooner or later you will run into a concept or so which will give you trouble and then it is best you seek guidance from an instructor or a teacher. It is necessary that you clear your doubts at regular intervals and don’t prolong things for long. Getting into a good coaching class is nothing to be ashamed off and if anything a regular coaching class will enable you to avoid roadblocks in your preparation.
Sample Papers
Even though there may be a complete change in the exam pattern or the expected questions altogether,it is important that you practice on the sample and previous years question papers available for the engineering exam you’d be attempting. You will know the existing pattern and have a fair idea of the type of questions to expect in the paper along with the time constraint.
Mock tests
The paper pattern, duration of the paper and the number of questions to be attempted in the given amount of time is not something you will be able to pick up on the day of the examination. A Mock Test tests a student’s abilities as it not only provides a similar feel of real exams but also helps in building speed and confident to face the exam. Furthermore, they can improve their performance to get an extra edge in actual exams. Try to build up an Engineering Entrance Exam Test Prep MCQ Question Bank
Time management
Time management can be learnt through thorough practice and regular test taking. So it is important that you practice it and practice it well.
Negative marking
Most the entrance examinations will have negative marking and everyone would suggest you stay clear of questions are not sure about. But some experts are of the opinion that you answer the questions in which you are confused between an option or two because there will also be a chance of getting it right.
