CCNA exam and subnetting.

DANMOH009

I used to revise subnnetting everyday for atleast 30 -45 mins a month or so ago, and i feel i am quite good at it. Since revising routing protocols though ive not spent so much time soley concentrating on it though.

My question is in the exam when you get the oportunity to write on a piece of paper, many people say you can write down the subnets and create a sort of **** sheet and use it in the exam when doing subnetting.

Now my first question is... is this true???

and secondly is it useful? or am i best not wasting time and just continue learning my subnetting my way so i can do the working out in my head?

Thanks

It's true...you get these before the exam starts, therefore anything you can jot down "legally" on that paper, will be useful. It will save time trying to work out the powers (2^10) or the masks of certain boundaries, etc.

Some centers give you a dry erase board and a marker, or most i should say...and you're not allowed to take it with you after the exam, for obvious reasons.

IMO it is useful, especially if you think you are weak in certain areas...
