can u send some gate material and any information about reference gate books for EC

Can you send me GATE materials for 2015?

PLZ GIVE ME THE INFORMATION REGARDING THE WHICH BOOKS CAN I REFERRED FOR GATE 2014 in E &CE BRANCH.

coaching is must,ace institute is best…..

I am sravika, will u please send me the model paper and previous question paper of gate 2014

i am 2 ece could you please send gate materials….that would help me……and tips to face the gate exams……thanks

I am 2nd year ECE please send gate material my ID is chandrika.lanka120@gmail.com

GATE is no more student friendly but rather very much business friendly for coaching institutes.Stats in 2013 say around 12 lakh registered and 9 lakh appeared & 1.3 lakh cleared and the race will go high 15 lakh plus in gate 2014.so why so many people appear for gate .Do all have passion for teaching and research no NO NO. It may be only 2 to 3%.Rest of all are looking for escape hole from unemployement and Low paying /torture ful BPO jobs .And these mass group fall a prey to coaching Institute earning in crores of rupees.The fate of our country today is here 12 lakh engineers are srtiving too hard for getting good job career but none what to change the system /politics which allow menace BPO sector exploiting engineers/corruption e.t.c. A doctor after MBBS able to earn on his own by visiting clinic.A laywer can earn on his own by advocating.But engineers alone looking for job/employment depend on others .Because engineers are not made as real engineers by education system which focus on theorys unable to solve real problems and earn decent living.People competing for PM post is hardly 1 or 2. But 12 LAKH engineers are competing for GATE.People by nature will have there own unique ability .There are not ready to explore there unique talent and try to apply them to our country and earn a quality living.And its not fare to measure the quality of mass people based on a complex theory based common question paper.That will not help to identify real talents.This is not hapenning any where in the world.Who is responsible for the generation of lakhs of under minded engineers.In our country the magnitude of impact created by Politician both positive and negative is huge when compared to engineers But there is no GATE EXAM for politicians? who are creating bill and making laws! and all unqualified /un ethical rude people are rulling us for years and poor engineers are by product of there bad system. Nobady can save them unless there themself find a way earn quality living.Today real estate brokers and contract builders are earning with half baked qualification are earning in crores.Need of the hour is engineers should realise that game around and find there own way to serve the world and earn quality living.All the best engineerS

well said.But let me ask you a question have you ever appeared gate exam or not ?

thanks……… for ur help

i need gate previous years question papers of free download…

Plz go to http://www.rgukt.in

thanx 4 ur information 🙂

thank u 4 ur help

thanks can you give some sample question papers.

they are available in the question papers link

nice info about gate inshallah it will be helpful for all of us

gud1

this information’s are veery healpfull for us………………………

post some new sample paper………. and one topper students’s contact no whose can i talk……how to preaper in gate pls suggest me…………thanks

post some sample papers……….

thx 4 detail..

get full details thanx………….

what about aptitude dude!

which engg. branch will be best for gate

ECE or CSE

i want to know that the syllabus which u give are better to crack the exam.and are all the question is come from syllabus topic. or i also study more than syllabus

I hv done B.tech In AEI wheather I M eligible to give Gate under another optional subject i.e. EC

gate electronics and telecommunication branch syllabus is also same as gate electronics and communication branch syllabus

sir, plzzzzz tell us about the electro. & telecommunication branch syllabus.

You can appear GATE 2013 ece stream. it is same sylabus for ECE

I am a Electronics and Biomedical engineering B Tech student under cusat kerala. Can i write GATE 2013 Exam ? Then What will bd the sylabus for gATE ? Is it same sylabus for ECE ? Pl give direction .

THANKS

thanks for the information

electronic and telecommunication AND electronic and communication are not same

you can give

if i am doing engineering in ece branch….. whether i am eligible to do exams under any other category?

sir i have pssed polytechnic frim bteup luckhnow what should i do to get a best rank in gate exam but i h’nt wish to do b.tech.please give me a fre e advice at my id enggpawankumar057@gmail.com

sir, is the electronic and telecommunication AND electronic and communication are same??

very nice info….!

mokka

i think its helpful if v try

good informatn it is useful for us thanq

useful information available here………..thanks

when wil be d gate 2013 conducted

i want d syllabus for gate ece 2013

at least try to cover 70% and u will get a good score….

good information posted in this site

I get in fact enjoyed account your blog posts.

hello every body, good information available here.
