hi sir,how can i minimze the time for solving yough problens.is there any trick which can save my time.

hi palash

cracking IIT JEE problem is always not use

there are many tricks to solve tough problem

but a single trick u can't use for every problem

tricks changes accroding to question that u can learn by solving question

more question u will solve u will learn more tricks u will develope ur own..

for example

if (a+x+x²)⁶ⁿ= a₀ +a₁x+a₂x2+........

then find a₀+a₃+.......

here if u will solve it will take lot of time

but u can take n=1/3 then u can find a₀+a₃+....... (only for objectives question)
