2 year drop for GATE exam .............????

Aditi Amrendra Student Expert 9th Dec, 2019

See, its a very tough call to drop for 2 years for GATE and its definitely not advisable but if you don't have any financial burden or any kind of pressure from home then you can do it but again its too risky and you will have to ensure that if you are going thia then you will give your 100% best and get a good rank because then only you will succeed or else the pressure will get upto you you will suffer badly.So, think smartly and decide wisely.

Good Luck

Is 70 marks in GATE is sufficient to get any PSU for electrical for general category?

apuroop sri durgesh 9th Dec, 2019

Hi Syam!

There were no measurements which could enable you to realize what rank/marks will cause you to get set in PSU's. It fluctuates from test to test, relies upon characteristics of the toppers,paper trouble level and selection of hopefuls who scores superior to you.And also it will be based on number of vacancies in PSU that particular year you are appearing for GATE exam. In any case, for a definite sure determination in a PSU then you ought to be in TOP 200.

All the best!


is agriculture biotechnology and biotechnology have different subject code in gate exam?

Avishek Dutta 9th Dec, 2019


There is no extra subject code for agricultural biotechnology in GATE exam. Both the subjects come under the subject code BT.

GATE 2020 for biotechnology will include

  • Engineering Mathematics,
  • Biotechnology,
  • Recombinant DNA Technology,
  • Plant and Animal Biotechnology and
  • Bioprocess Engineering and Process Biotechnology...

To get psu jobs throw gate,upto which rank it is possible

apuroop sri durgesh 9th Dec, 2019

Hello Mahesh, we cannot judge for a single rank because through gate passing score, one can be eligible for number of PSU's. There are Miniratnas, Maharatnas and Navaratnas you can opt for basis on you rank of GATE, you can have a clear cutoff for different companies at .

Hope this helps.

Thank you.


the Boolean expression for NAND gate is

Rakesh Sai 9th Dec, 2019
Boolean expression for NAND gate is represented by a dot or fullstop symbol (".") and a bar or overline (-).
If A and B are inputs then NAND gate expression is
([A.B]^ - ).
NAND is negation of AND gate so it's truth table is simple. Symbol ,Truth Table are provided in the link.
