You can improve your Arabic typing by choosing to use one of the many free download or shareware tutorials that are available on the Internet. For example, BestSoftware4Download.com has a free download tutorial that trains you how to use an Arabic keyboard step-by-step.
Another option is to purchase shareware. For $20 you can download Arabic Typing Tutor 2 (see Resources). One of the perks of this software is it "is written in order to increase your Arabic typing speed, through teaching the basics of how to put your hand on to the keyboard and give some training examples."
When using a free download or shareware found on the Internet, run your virus program before downloading.
