[Zecc]

Less than six months ago I found this same site and I was practicing religiously multiple times a day. Several weeks ago I interrupted my practice for one reason or another and last time I tried my score had dropped to below 40%. I need to start practicing again.

I haven't learned the full alphabet yet. I'm still missing letters q, g, h, z, x,c, v and all the digits.

Something I've found interesting is how much difference it made changing the tone frequency. My brain definitely got used to a certain tone initially, and when I first tried changing the tone my recognition ability dropped quite a bit. So now I change it occasionally to keep my brain on its proverbial toes.

I wish there was a way to practice just the letters I have more difficulty with; namely, the ones which were added later.
