I've started this thread so that we can all co-ordinate our preparation with respect to academics for GDPI.


Everyone is welcome to share any inputs/material/concepts they can.

I know studying acads is boring, but a coordinated effort should help all of us. :)

@bluechameleon18 ai re ekhane
@ashishpai2001 , GATE ka syllabus hai na ye?

Humko ye saara toh nahi karna...

RSA aur higher math karna pade in case, C se call ho kisi ki..
Second year ke saare core subjects aane chahiye imo.
@ashishpai2001 said:

Ye sab to Engineering me b nhi padha tha
Just kidding. Start kahan se karen thats the ques.
Itna lamba syallabus dekhkar to darr lag raha hai
PS: @vijay_chandola bhai apki upasthithi chahiye is thread par

IMO- exp candidates apne fields se kuch padhe. for ex i work in a company that deals with mobiles in the simplest sense so i must know cdma , gsm etc . Next i must learn about signal processing. and a little bit of milman halkias also can be done...


Itna padhne ke lie aur 4 saal lag jaaenge to thoda soch samajh ke padhna hoga......

Bhai me toh karne wala hoon, fir tumhari marzi. Warna aur ek option hai: Past interview questions forum se chaantke karo.
@ashishpai2001 ye better option hai...
warna itni to kitaabein bhi nai hai mere paas..

Kitaabein toh mere paas bhi nahi.. Kisi k paas Microprocessor ya Digital Electronics ki e-book hai ??

abe apun ko milke karna hga :thumbsup:

yar tu commuciator me dhund na mjhe...maine tujhe dhundne ka try kia tha...ni dhund paya....mjhe dhund tu

hey guys, it seems this thread is for ECE guys...btw I am a btech in IT 😞 , is there any thread for poor souls like me to discuss regarding GD/PI. I searched but could not find one...plz reply

yar kahi dikh to ni rha hai ..IT CS ka.....issi pe kar le yar taiyari...jab tak kch aur ni aata.....main bhi IT ka hun...
@FSOG @saikatha besharmo naya thread ban lo....

itni beijjati k baad to banana he parega naya thread, arey IT, CS parhe hai, isliye koi ijjat he nahi bachi...... 😃

bana yar tu issi bat pe 1 thread...and tag kar dena mjhe and Firsty ko
@Omkarp Attended many interviews, they ask only basic questions from engineering guys(especially ee and ece). Like from an electrical engineer they may ask about machines, transformers, few formulas like synchronous speed etc, how fan works, AC/DC...So no need to do in-depth study if you are short of time. Just do the basics and that will be enough :)
