All you have to break IIT-JEE is only that shear frenzy for that fantasy of your's to learn at IIT. 

For the following 4 months in your grasp simply center around all the vital themes that cover 70% of the inquiry paper. 

Spotlight on the traps more instead of going for long speculations. 

Practice day by day one inquiry paper comprising of what you realized entire day during the evening. Try not to center around the imprints however center around the time you take to unravel each inquiry by moving toward it effectively. 

Begin with science I would recommend, covering inquiries from P-BLOCK and ORGANIC part quickly. 

Attempt to finish entire parcel of inquiries from science the primary month. 

I would propose not to purchase any books like JEE-MAINS in 40 days. 

Kindly don't purchase such things rather download earlier years question papers and understand them these books really eradicate your long hypothetical ideas and give you futile alternate routes which don't help at right minute. 

going to the following month go for maths. 

co-ordinate geometry is the best to pick first in maths. this theme covers relatively every inquiry . you have to get order over it. each inquiry is mixed with co-ordinate geo's ideas. 

build up your own traps to settle addresses as opposed to going for thick books and getting out nothing. 

in maths territory you should be quick accordingly and getting the inquiry right. coz many-a-times it happens that we never get the inquiry itself and we keep on solving for a long time. 

hone immense. cover relatively every inquiry from the previous 10 years question paper. 

at that point comes the following enormous unnerving piece of PHYSICS . 

this area gets you down the most in the event that you haven't hone enough. 

I would propose to see through the ideas of electromagnetics and power . 

likewise rehearse questions that are blended of pulley ideas, power and movement relating. regularly addresses come that are of 5 tremendous fields :)

hope this helps
