**GATE** stands for Graduate Aptitude Test for Engineering is one of the toughest test, an all India Examination that basically test the comprehensive understanding of various undergraduate subjects in **Engineering** and Technology. It has been known for testing the engineering basics in a smart way. It need the effort of mastering an entire course of engineering (30+ subjects) which gives it a level of toughness in itself. It is jointly conducted by Indian Institute of Science and seven **IIT’s** on behalf of National Coordination Board-GATE, MHRD, Govt. of India, Department of Higher Education. GATE Score can be of help like it can be used to get into various Post-graduate programmes in Indian Higher Education Institutes that too with financial assistance provided by MHRD and other government agencies. It may be used by Public sector units for employment screening purposes.

how to prepare

http://blog.oureducation.in/gate-exam-syllabus/ try this else be precise with question , you want to know about books then http://blog.oureducation.in/reference-books-gate-e-c-engineering/

sir what is correct way to prepare gate exam

I HAVE OPTED FOR ELECTONICS ENG(NOT ELECTRONICS AND COMM) CAN I APPEAR FOR GATE EXAM

sir can you pls say …. whether the books we have used for our subjects are enough or not?

how can we prepare for the gate without any specail tuiton by our own

you can get GATE 2015 syllabus @ such a nice web site to prepare for gate without any coaching

Hai friend, you can prepare for gate without any additional classes by downloading some pdf files or model exam question papers from internet. By these materials you can prepare for your own

i heard that many changes are going to happen in gate 2015 is it true?if it is what are the changes?and one change i heard is computer shoot i.e.,when we answer an easy question we get difficult or viceversa.bt this change is not fair sir because one who can’t ans an easy question in one subject can answer a difficult one in other subject so overall a student may have a grip in some subjects maynt have in some other subjects.so they can answer question based on subject they have a grip

complete details of changes in GATE 2015 you can find at
