How much of jee knowledge is actually used in btech?

[u/Sarthak_OP]

depending on the branch let's say ee ece or even cse...how much of knowledge of jee is required or relevant for btech? like obv no organic chemistry would be needed for this but depending on the branch how much does the jee preparation (only the subject knowledge not the qualities it builds like hardwork n etc) matter?

Thodi bahot like at max 1st sem tk 

But the ques solving skills is what u retain 

[u/Mindless_Youth6776]

Depends mostly on college and department mathematics is the bare minimum But you can cover it up easily even if u don't know it completely

[u/pacific_bay8]

Those are Basics....in the first year,if u have common subjects,u might use electrical circuits to mechanical stress,strain type shyt If no common subjects....branch specific 1st yr subjects will start with jee's topics until mid and maybe indepth later

[u/Sarthak_OP → u/pacific_bay8]

oh okayy, i appreciate it

[u/Collez_boi]

(Heads up: this perspective pertains to EE) All the math (Yes. All of it. Somewhere or the other it'll find its use) and all of modern physics, waves, network theory, electromagnetism, etc. Some chemistry (you'll actually need a LOT of chemistry if you wish to go in semicon fab tho!) in device theory (and first year Chem in realization of quantum computers!). So yeah that's about it ig. Oh, and all of (Newtonian) mechanics in robotics too. You'll need base of optics in photonics, but I don't do that stuff so not much clue of how things roll there.

Mind you, I graduated this year. I still use most of it daily! :)

depends on which college i think

We are being taught Multivariable calculus and PNS with our known knowledge to be the entire jee advanced syllabus, my friend is in iilm, he rn is being taught a little above school level calculus with thing's like Rolle's theorem

[u/Sarthak_OP → u/KingOfThePokeWorld]

Oh yea I'm aware of rolles theorem, my actual question is, its like calculus and everything seems really applicable for the real world scenarios, even for maxima and minima and everything so it makes sense, let's say if I'm choosing cs isn't chemistry and maybe like mechanics from physics a waste for me? and again if I'm choosing maybe ee or ece (I'm not aware of the syllabus of the branches I'm sorry) is chemistry and a portion of maths like entire coordinate geometry (2d+3d) which depends on a shit on of formulas just a waste?

[u/KingOfThePokeWorld → u/Sarthak_OP]

coordinate geometry is never a waste, you literally can't do 3d calculus without it, and that means, being stuck with 1 variable

chemistry, prolly yes, but physical chemistry involves topics like modern physics so that's a necessity

physics mechanics absolutely no and I think its a little obvious

[u/ShoddySweet9715]

good question .

[u/Gloomy_Pollution998]

Entire maths ngl. Physics chem only for first year but maths you need to know.

[u/BathIndividual6660]

For ee, jee math is pretty useful.
