If you don't know how to type, then data entry isn't for you. I learned how to type in high school about 20+ years ago and everyone laughed that I was taking a "girls course" since it was on typewriters and that was a woman's job back then. Now I can still type almost 90 words a minute.
No one is going to do the test for you, and even if they did, then what, you show up for work the first day and can only type 5 words a minutes by hunt and pecking and you're fired anyways.
Go do some learn-how-to-type exercises online and hope they don't have a high score set for the job.
