Typing Speed test 2

1. Rondom string is generated and presented to the user
2. User enters the given string in a Text widget.
3. If the user entered string matches with the given string then a new string is given after removing the old one. User is allowed to enter fresh string.
4. Before adding data user has to click one Start button. This button will enable the data entry and the entery widget will be disabled once time is over.
5. One countdown timer will show the remaining time
6. Total number of chars entered in text widget will be displayed once the time period is over.
