how should i can get 1st rank in iit jee

dude if r so small but still look so confident
well iit is not like and 24 hr labour is also not possible specially for eight class guy
WELL I TELL U THE FACT IS THAT U R THINKING UNREALISTICALLY AN IT IS COMMON TO HAVE SUCH FANTASIES AT UR AGE WHEN U HAVENT SEEN WHAT IS EDUCATION AND COMPETITON IN INDIA
coming first in ur class or school is a different thing and topping iit is different 
SO U SHUD NOT THINK LIKE THAT BECAUSE IIT CHEEZ HI KUCH AUR HAI
BUT YAA U HAVE TO AIM THAT AFTER 12th u have to clear iit jee in any chance an it is ur dream
AND FOR THAT U CAN EVEN START WORKING FROM NOW ONLY 
BUT DONT GO FOR IIT COACHINGS TILL CLASS 11TH BECAUSE ITS USELESS
till class 10th what u do is improve ur science and maths problem solving skills
for eg when in maths when u finish ncert chapter in maths then make ita habit to praccticee more tougher questions and solve them without looking at solutions and in science try to grasp the concepts and basics
this all will help bcs when u will do class 11 th and 12 th physics ,chemistry, and maths u will only succeed with hard work and full underrstanding of concepts of entire 11th and 12th
ok now work hard from now onwards specially in maths and science and also dont neglect ur other subjects try to be an all rounder rather than a genius of 1 or 2 subjects
and 24 hr labour is not healthy n u r still a kid 
ok best of luk and one more thing be regular in ur studies and make this attitude of regularity and carry it till the day of iit exam after 12th class 
SO IN SHORT ---
BE REGULAR
STUDY HARD
WORK HARD ON MATHS AND SIENCE FROM NOW ONWARDS AND DEVELOP AN ATTITUDE FOR THESE SUBJECTS
AND MAKE REALISTIC GOALS BCS TOPPING IIT IS JUST A FANTASY 
HOPE I HELPED U AND MY AIM WAS NOT TO DEMORALISE U BUT JUST TO MAKE U SEE THE REAL THINGS BECAUSE I ALSO USED TO THINK LIKE THAT AT UR AGE
U CAN EMAIL ME IF U WANT TO ASK ANYTHING THROUGH YAHOO ANSWERS
BEST OF LUK ONCE AGAIN AN GIVE ME 10 POINTS IF I HELPED U IN ANYWAY
