IIT-JEE problems

utkarsh009 · Mar 16, 2011

^^yah i gave the second round of nso but not imo. it was really bad luck for me not even getting selected in the first round. imo 1st round was too easy and i made 5 silly mistakes. only 2 students who did 3 and 4 mistakes respectively were selected from class 9. (from our school). btw is your board exams over?

hey everyone! the most unlucky guy in the world, "utkarsh" is replying here again. i got AIR 4 in nso.

pauldmps · Mar 16, 2011

Why unlucky ? You got a great rank. What prize are they awarding you ?

utkarsh009 · Mar 16, 2011

@pauldmps: they'll be giving me rs. 5100. and you asked why unlucky? thats because my father wanted me to take him to delhi for recieving a prize just like i did in class 7 when i got AIR 3 in nco. now they'd not be calling me. i broke my fathers heart. i wasted my whole year. secondly, 1, 2, 3 ranks would be getting 51k, 31k and 21k respectively so am i not unlucky getting 5.1k just because i got rank 4. :-(

AIR 4 is not a joke. Imagine getting that rank in about 30k students appearing for the exam. My personal best was about AIR 550 in NCO.

Also the amount of prize has no value. It is the prize which needs to be preserved & cherished. If I were to get a cheque worth 5.1k, I would preserve it instead of encashing it.

^^my personal best was AIR 2 in UCO(unified cyber olympiad) which is organised by unifiedcouncil (which organises nstse) in class 7. it is conducted only till 10th std. and was started 2 years ago. i have still not been able to get AIR 1 but probably this year i'll study hard to achieve AIR 1. ;-)

huh!

well i have already wasted all my prize money won till now in upgrading my computer. (see my signature). and i'd probably be wasting another 25k i'll be getting from fiitjee for the 9th class session in buying gfx card and few other stuffs. but i'll be preserving the next 75k i'll be getting for the next 3 sessions. ;-D

You don't have to beg your parents for pc upgrade. Now isn't that great ?

utkarsh009 · Mar 17, 2011

^^i have to beg! because they dont like computer and think that i am wasting my money. i am still not sure that they'll let me use those 25k!

pauldmps · Mar 17, 2011

That is a common problem with parents. I haven't upgraded my PC since 5yrs. Atleast they've promised me a laptop this year.

nims11 · Mar 17, 2011

same here, The monitor of my PC went black many months before and my parents dont want to get it repaired as they think i will pay less attention to studies. now i have to use a very ancient laptop for everything. also i have not been allowed to use a single penny of 15k i received from FIITJEE. i too have been promised a Laptop if i get admission in a collg.

pauldmps · Mar 17, 2011

For what are you all receiving cash prizes from FIITJEE ?

utkarsh009 · Mar 17, 2011

^^cash scholarships as a reward of FTRE (fiitjee talent reward examination). i got AIR 34 and have been awarded 100% fee waiver (though i had to pay 30k as structural fee for 4 years) and 100k cash scholarship which i'll be getting over 4 years.

Same case here. I played games on my onboard graphics.

Fortunately, my mobo has ATI Raedon Xpress 200 series integrated graphics which give better performance than Intel HD ones.So I did enjoy playing games like FEAR & HL2 at 800x600.

I'm hoping that things will change soon !

Dude!! me too!! i thought i was the only one not to see a gfxcrd!!

btw seems FIITJEE is increasing the cash scholarship!! i got 15k + 100% fee waiver(had to pay 20K as admission fee) for AIR 138 and a friend of mine got 40k + 100% for AIR something btween 40-50..., a year later one of my junior got 40k for AIR 170!!

This may be useful to you guys

*www.youtube.com/user/khanacademy

It has some solved IIT problems in math....may be useful while revising

all the best guys

utkarsh009 · Mar 17, 2011

@nimesh: actually it also depends on your class. if you are in std. 9th then you'll probably join 4-year course so more scholarship. even if you opt for 2-year in std. 9th then they will half the scholarship. all information is given in fiitjee brochure. but yes they are increasing. sthita got AIR 5 and got 100k. next year i applied for the same course and got 100k for AIR 34!!!!!!
