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 82% accuracy. Three stars need 36 words a minute at 94%, 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 C++, C#, F#, email@test.com, price: $99, 50% off, A+ grade, 100% complete.
