Basically I am looking for advice on a quick way to learn Colemak. I am now about 50 wmp using Colemak. But it still doesn't flow right. I have learned Qwerty and was Dvorak user for about a year and a half after that. I have been using Colemak for close to three months now. I want to know if there is a good fast way to learn Colemak better either online or install a program on my computer. By the way I have both a Windows computer and a Mac. My goal is to reach 70+ wpm and hopefully faster after that. My biggest problem is I start typing fast but I always input the wrong key when I go fast but when I go slower I am 100% accurate. I would like to overcome that. So I am asking is how you people learned Colemak and any other way I can improve. Thank you

p.s. I have a hard time when I practice my typing and the letters r and s are next to each other in the words. Usually make a mistake when that happens any way to overcome that too?
