What is the first goal to accomplish in analyzing a complex series-parallel circuit?

For me, the first thing i always do is,

I try as much as possible to reduce the number of resistors

Consider this circuit

It's always good practice to reduce like here, you can combine the resistors of #3Omega# and #4Omega# by calculating their resistances #" R" = (3xx2)/(3+2) = 6/4 = 1.5Omega#

So now we are left with two resistors instead of three.Got it?

The choice of the resistors is not always the same, it depends on the question!
