Start at 35wpm and you’ll copy at 25 in no time

Fantastic approach:

“You can copy 25 wpm in three weeks, with just 15 min a day practice. Start at 35 and work down… You listen, and listen some more. Use the W1AW practice run that starts at 35 wpm. After a few weeks, 25 wpm will sound slow, and you should be able to write the characters.”
