## GATE Aerospace Engineering Statistics

Below are some statistics of GATE Aerospace exam. Note the data provided gives you idea about complexity and competition of this paper.

- Number of candidates registered for the exam – 4500 (approx)
- Number of candidates appeared for the exam – 3500 (approx)
- Number of qualified candidates – 648
- Percentage of candidates qualified – 20% (approx)
- Maximum marks out of 100 – 82.00
- Minimum marks out of 100 – 19.67
- Average marks – 39.42
- Standard Deviation – 11.85

The number of candidates appearing for this exam is less compared to other papers like Electronics or Electrical. The success rate of this exam is low. One out of 5 candidates got qualified in the exams.

So you need proper preparation material to succeed in this exam. Later in this article we will provide all details you need to crack this exam.

Also the maximum marks and minimum marks difference is high. The average marks in 40. This is close to minimum marks. So majority of candidates score in range of 50 to 30. With some students scoring more than 50 and some less than 30.

So if you can score more than 55 or 60 then you will have good ranks.Understanding difficulty of exams help you plan your preparation as well.

## GATE Aerospace Engineering tests

We have created set of online tests for candidates preparing for GATE Aerospace exams.The online tests are free.You can try them unlimited number of times without any restriction.You can click on the links given below to try the online tests.

Note the tests comprise of previous year GATE Aerospace exams questions as well as questions important for current year exam. SO to have edge over other candidates practice all the questions in the online test.

I have also outlined the features in this post.You can straight way try out the tests or read on the features and make your decision.For best results I recommend practicing all the online tests listed below.Each test has separate set of questions.So if you miss one test means you are missing one set of questions.

Each and every question is prepared with upcoming GATE Aerospace Engineering paper in mind.Solving every practice paper will give you great boost before the exams.The best part is we have covered important portions of GATE Aerospace syllabus while creating the questions.

You can also see score of other students who have attempted these exams after finishing the tests.This will give you an idea of your preparation level compared to others.The exams have time limit and negative marking just like real GATE exams.

## GATE Aerospace Engineering Book 1

Below are the features due to which this book is recommended for GATE Aerospace Engineering exams. Note there are not much books for this exam. So this one fills a void as well.

- Last Eleven years solved papers of GATE Aerospace Engineering exams
- The solved questions help you understand trend of questions asked in previous year exams
- The solutions are detailed so you will be able to understand the solution better and grasp the concept behind it
- Six mock papers will help you get idea of new types of problems important for exams
- The mock papers are based on previous question pattern along with questions important for current year exams
- The book also has Syllabus outlined so that you have better understanding of it and can refer it while preparing
- The book is written by authors who have wrote books on GATE Aerospace Engineering for quite sometime
- The book is one of its kind. There is not much books available in market on this topic.
- The book is best seller in its niche

I have shared link of the book below. You can buy the book online from below link at good discount. Other places the price is high so you have to pay more for the same book. Note there are multiple editions of this book (viz 2015, 2016, 2017 and 2018).

You should be careful as to buy only 2018 edition book. Below link is for 2018 edition book only.

## GATE Aerospace Engineering Book 2

This second book is not a normal hard copy book. It is kindle edition of the book. The book serves purpose of candidates who want to study while on go. I have mentioned below some of pros and cons of this book. The book has many limitations.The only reason to recommend this book is that it is digital version.

- The book is kindle edition. So you can read the book any time like while traveling in public transport or college. You do not have to carry your book for preparing
- The book provides solution of random questions asked in the exams
- The book only has 45 pages.
- The number of questions covered is approx 150.
- The solution is not that detailed. The first book has more detailed solution of problems.
- Number of problems in first book is way more than this one
- Note the book is free for kindle unlimited. So if you have kindle unlimited then you can read this for free
- You can also have a free sample before buying the book. The free sample will help you evaluate book before making a decision.
- Note the book does not have too many users and author is not well established.

## GATE Aerospace Engineering syllabus

GATE Aerospace Engineering syllabus is divided into multiple sections.You should prepare section wise.It will help you track the preparation and topics covered.Core topics are more important.Majority of questions are asked from Core topics.

So while preparing focus more on core topics.Once your core topics are over you can focus on special topics.It is not advisable to read special topics before completing core topics.The below syllabus is taken from official website of GATE exams(syllabus link).So the syllabus presented below is reliable.

## Conclusion

You can also post your questions.I will try to answer most of them.Also many candidates hare their experience you can get benefited reading their experience. The online tests also feature previous year GATE exam questions with answer.So following them will give you good idea about pattern and importance of topics.

As mentioned above there are lack of GATE Aerospace Engineering books in market.I have mentioned two different kinds of book. I would recommend the first book. It is continuously updated over the years.

The second one can work as a supplement but not as a complete book. Along with above resources you can also use free resources available on this website. The site has solved questions and answers from previous year GATE exams along with sample questions. Also there is free mobile app as well.
