Hi all, I just want to let you know how I did mine on the day. I already knew before hand from a friend of mine who had done his the week before with GTR the following info. The first test goes find one of the same upper case letter, this lasts 2 minutes. The next test is one upper case and another lower case letter. These are 2 different letters, but the same throughout. This lasted 2 minutes. Final test is the same first upper letter throughout, and then the other letter is the first letter of each new line you go down to, so the letter that starts each line is the other one your looking for on that line. When you go to the next line, then its the letter that starts that line that you are looking for until the end of that particular line, and so on.
The first letter mentioned at the beginning always stays the same. Hope that wasn't too confusing! This third test lasts 3 minutes.
When you do the tests, after your time is up on each test it then automatically gets submitted and you cannot review it in any way. You also have no way of knowing how you did.
One idea would be to record it with your phone pointing at your computer screen and recording it. At least that way you can see how you did afterwards. You can also see how many lines you did and if you missed any. Mine were test 1, 22 lines, 0 misses. Test 2, 26 lines, 0 misses, test 3, 22 lines, 3 misses.
I felt it also helps to say out loud as your doing each one, what letter your looking for.
Thats a pretty definitive summary of my experience of my test. Hope it all helps. I'm still waiting for my DMI so will post my experience of it once I've had it.
