A lot of people type with two fingers, and thus type around 10 - 15 words per minute. After completion of this course you should be able to type at least 45 words per minute, and even faster if you type often. If you at your job type nine hours a week you will be able to save the six out of these nine hours provided you triple your typing speed. That will be nearly 300 hours saved a year or seven weeks extra holy days a year. If you have 30 years left before you go on pension the course will save you about 230 weeks work. Are you self employed you will be able to stop working four years early. Or, if you could convert your increased typing speed into a pay raise, you could get four years extra payment before retirement. Learning how to touch type is probably one of the best educations you could invest in. And it won't cost you any money. You can here: calculate your own personal benefit from improving your typing speed. How ever it works out for you, you have probably never met a person who regretted spending some time improving his or her typing speed.
Third, Keybr.com lets you introduce as few keys as possible to the lesson, adding more keys automatically when it decides that you are proficient at the current level. When you only start learning it generates lessons with words from a very small alphabet of the most frequent letters. When your typing speed for every key in that alphabet reaches certain threshold, the algorithm adds the next most frequent letter to the alphabet. And so on, until the next letter. This way you will learn the most frequent letters first, and the least frequent ones later.
The less work your fingers do to press the keys the faster you will be able to move them. Most keyboards require only a light touch to register a key stroke, so there is no need to mash the keys down. You should type with the minimum force necessary. You will type faster and put less strain on your body. Typing involves muscles not only in your fingers, but in your hands, arms, back, shoulders, neck and head.
Mastering typing skills takes training and practice. Practice on a regular schedule, 10 minutes to an hour per session, depending on your energy and focus level. As Vince Lombardi said, “Practice doesn’t make perfect, perfect practice makes perfect,” so it is important that you practice at a time and place where you can maintain focus and accuracy. Eliminate any potential distractions. If you find yourself making lots of errors, slow down and find a way to regain your focus or call it a day. The goal of practicing is to build muscle memory. You do not want to “learn” bad habits and mistakes.
