This level belongs to Caps & Symbols — master shift combinations and special characters. It drills 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.
The target is 20 words a minute at 85% accuracy. Three stars need 40 words a minute at 95%, so there is a reason to come back to a level rather than pushing on through material your fingers have not absorbed yet. Accuracy is worth more than speed here: going fast and correcting constantly is slower than going steadily.
Words you will type include 123, 456, 789, 2024, 100, 999, room 101, page 42.
