In Just Five minutes.....

I give you five minutes.... Honestly would you be able to tell orally without referring, without taking more time, you are able to say
A to Z in the reverse?
That is, Z, Y, X, W, V. U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, B, A?

Post yes if you can do it!
Don't worry if u can't, Not many do it!

Yes, I can.

You missed B, I added it in.

I too didn't know that smile

Those with elementary training in typewriting have a very good chance of doing it! smile

Re: In Just Five minutes.....

I provided a link in a thread called 'How Low Can You Go?' in which you had to type the alphabet forwards or backwards in the fastest time possible, then submit your score. It was a nice little flash game.

Re: In Just Five minutes.....

I agree. Five minutes is too long, unless you count the time from when the person first starts reading your post to the time they finish saying it properly.

Re: In Just Five minutes.....

I agree with landof+. 5 minutes is too long. Maybe 1 minute is okay, 30 seconds a challeng smile

This is a test for you to see if you can do a simple calculation without a single mistake in a minute. Single minute, and you are disqualified. Just 60 seconds.

Subtract 7 from 100, then 7 from the result, and keep continuing this process as long as you can. What positive number would you be left with?

Re: In Just Five minutes.....

Thats remarkable, Zach! Very well done!
Normally, even those good in counting may stumble and get disqualified!

Re: In Just Five minutes.....

I can say it in 1-2.5 seconds. This is because I already knew it from memory, many years back.

Re: In Just Five minutes.....

Can't you just subtract 70 and then go from there? I could do it in 3 seconds if that were the case.
