it depends upon how you read and grasp the subjec matter

step 1 - varies from 6-8 month
step 2 ck - varies from 3-5 month
ste2 cs - varies from 15 days to 1 month
step 3 - it depends 1-2 month

so you can figure out that gap between them its continuous.

but some of my friend have given step 1 then worked for another one year and then gave step 2 but other are same
