(This posts and details for basically for EC and EE only but can be useful with sensible modification)
Total 9 subjects out of which how many have you prepared. As per rough guess, every subject will hold around 5-6 marks on average. That means 2-3 question. As per rough analysis, every subject has 5-6 main topic and concepts revolve around this topics. So from the above statics, our GATE paper may hold upto 50% of the question from the syllabus.
When I was just started thinking about GATE, my seniors, teachers and colleagues always used to say only basic and conceptual questions are asked in GATE paper. And I am 100% agree with them after looking at the previous years paper. But one thing we should be aware of. Engineering or GATE syllabus is basic only. So my suggestion towards smart movement will be study/revise all possible topics, practice them well and make of habit of looking at previous years paper to get the great insight of the structure.
This year IIT Delhi is organizing, ofcourse everyone knows it. What you guys think, organizing means only setting up the paper? Ofcourse not..!! from declaring dates, then distributing forms, maintaining all candidates well fair and allotting them centres, management of exam centres and what not.. So in last 2 weeks if you think IIT Delhi is doing great research in communication sector so communication will hold maximum of marks, then it will be utter non-sense.
Coz logically, communication have mods-demods circuit. And working of these circuits comes under the syllabus of Analog Circuits. Equipments required for the circuits are from Electric Devices, stability of the operation of these mods-demods are from Control system, study and effects of Noise and other frequency spectrum on the data signal can be studied under Signal and System and designing mods-demods will need configuration of resistors, capacitors and inductors i.e. Networks. So yes, now I can say IIT Delhi will only set paper on Communication and related syllabus. Hahaha. It means all subject. This is an example of communication. You can even think of any subject and you will find other subjects are inter-related with it (Do this analysis after GATE exam). So don't act smart and stop looking for shortcuts.
By the way recently I got the secret for SUCCESS. It is a simple phrase. HARD WORK. Many of us just avoid working hard by saying we had taken a SMART way. But now after all the SMART WORK done, there is no alternative to HARD WORK. So last 11 days to go. Make day and night as whole, and study hard. Cover as much syllabus you can cover, practice as much as you can, and finally your GATE score will be improved some what on 15th March.
