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.
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 Recommended Book
I would recommend below book along with above online tests.You should use both the resources for complete preparation for the exams.remember GATE exams are tough and thorough preparation is required to succeed in the exams.
I have also shown the updated syllabus of GATE Aerospace paper below for your reference.You should prepare topic wise.The online tests also represent sections more important for GATE exams.So solving every test will help you get an idea of important sections.You should focus more in important sections and less on special sections.
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.

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. Consider sharing this post in case you found it useful.
