Yep. However, I've noticed that my scores tend to deteriorate as I
get older. Probably started when I switched to decaf. Also, there
was a drop when I started using reading glasses:

"The poorer performance by older adults may be characterized by a loss
of efficiency in visual search," stated the researcher." If it takes
a few milliseconds more for someone older to read the symbology,
multiplied by a few hundred questions, it becomes a significant
factor.

I can get away saying that, because I consistently score in the 99th
percentile.
