    I recommend you learn it, and be prepared to use it on the exam. You can write things down on the white board they give you in the exam room. But you will be expected to subnet in 30seconds or less. Its something that will follow you in all of your Cisco studies.

    How you get it done doesn't matter. If you can do it fast enough by using your toes go for it. If you are having to manually work it out though it's going to be time consuming.

    Why not just take the time to learn it well enough that you can just do it in your head? It's a useful skill for your career as well. You don't want to have to walk out of a meeting to grab some scrap paper to work out a subnet.
    An expert is a man who has made all the mistakes which can be made.

    Time management is probably the most important part of the test assuming you know the material.
    Subnetting questions are what allowed me to catch up and finish the CCENT with 7 minutes left. CCNA I had 2 minutes left.

    You don't need anything but $150 to take the CCENT so by all means go for it.

    As long as you can do it within seconds, you can do it on paper or in your head.
    You have a white board and a marker w/ you when you take the exam.
