I am in need a "robot-like" Fast subnetting trick(s). Plz-plz links.
Evey time I'm thrown a "hard" mask, my heart sinks, and I freeze up and take too long on doing subnets. I need a no-thinking, do-it robot-like method of passing the exams.
I don't need explanation of what subnetting do, why and all that, I know them well. I just need to be able to do them QUICK, 'cuz I have this mental block and try to analyze too much of what the exam is asking me.
TIA
