What are your opinions regarding:
* number of times to practice per day
* length of time per practice session
* length of time to struggle before looking at the layout chart/diagram
* what sort of practicing works best: software, typing speed tests, just typing various words *n* times, etc.
* if tutorials are recommended, which ones?
I've never used any sort of typing tutor software. When I learned qwerty (and later dvorak) I just sat down with a paper key chart and typed different words maybe 10 times each until it felt like I could do it alright, then moved on to the next word. I suppose this worked ok. I've never cared about being a speed demon, but have pretty much topped out at 65 wmp dvorak.
