First you gotta go to Bharti Office (Transit Camp in Rawalpindi) !
Then you get forms to register yourself from there.
They will inform you abt the date of initial test @ Transit Camp.
If you clear that, then you are given a medical Test date.
Clear that and you'l get a call from ISSB.
You are informed of a ISSB center in different locations.
Once you get to ISSB, there will be a variety of tests there, mental and Physical.
