Education and Career Forum

I'm a third year student . i would like to appear for the gate exam. I'm going to choose an instrumentation paper. but i'm not sure about that how many subjects i have to prepare for the exam and i would like to know about the rules and regulations for appearing gate examination.

Dear Friend

Apart from core engineering question there would be some question from GENERAL APTITUDE
which comprises of following;
Verbal Ability:
English grammar, sentence completion, verbal analogies, word groups, instructions,
critical reasoning and verbal deduction.
Numerical Ability:
Numerical computation, numerical estimation, numerical reasoning and data interpretation.

There is no age limit for the examination.
3rd year/ final year/ passed out engineering(or M.Sc.) students are eligible for the exam.
You should visit GATE website for any further detail.

http://gate.iitm.ac.in/

there is a no age limit for GATE exam.
GATE is valuable for only one year.
B.E final year or pre-final year are eligible for writing the exam.
the subjects you study in B.Tech degree all the 8 semesters.

hi dear
for GATE exam
you prepare for your only branch subject,what you taken in B.TECH.
and some apptitute question in R.S.AGRAWALA books
that is very use full for you ........

if you once crack the GATE then your future is bright ......................

for rule and regulation please you visit GATE website:---

http://www.gate.iitb.ac.in

GOOD LUCK...............

how to stady time managemant

How many subjects was there in an instrumentation 3rd year/final year exam in 1982

i am in first year . please tell me about the books i should prefer . I am doing b-tech in mechanical.

how many time i'll eligible to faced in gate exm.

trell me the each subject marks in cse gate

My dear friend ,
Actually it depends on your stream.
Subjects will change from one stream to another.

As I'm from CSE background I can tell you those subjects :

1.Probability

2.Graph theory

3.Partial differentiation

4.C language

5.Automata

6.Compiler

7.Object oriented programming

8.data structure

9.Digital electronics

10.Software engineering.

- join a gate forum .

-practice regularly .

- take online test .

-concentrate more on concept building rather than just studying .

- work on your aptitude .

Iam a btech 3rd year CIVIL ENGG. student. Wat r the subjects should i go through for writing gate xam..?? Plz give me the details of subjects i should b perfect in.

would u like to tell me abot the subject should be prepated for gate exam.i am final uear student of elecyronivs and communication

hi! I am a third year civil engineering student....I want know that how much marks I have to obtained to appear gate exam and how many subject I have to study for gate exam?

Dear aspirant,
Here I am sending a file which tells you all the details of GATE 2013.
ALL THE BEST

How may times i can appear and how mny year is valid this GATE ranking and also where this ranking required , except M.tech.
