To determine your progress TypingMaster monitors two factors during the drills -- accuracy and typing speed.
Monitoring Accuracy
Since good accuracy is the foundation of proficient typing skills, all drills have an accuracy goal. TypingMaster monitors whether you reach the goal and gives you feedback after each drill.
Monitoring Typing Speed
TypingMaster constantly monitors your typing speed as well. The better your speed, the sooner you can move on -- as long as you also reach the accuracy goal. However, with a typing speed below 15 Words per Minute, you'll benefit from typing for the full duration of the exercise.
