In training lession capital letters exercise there is confusion between capital "I" and small "l"(L)
because in this test word are non meaning words so we are facing problems
for example: "AI" what would you type for this "AI" stands for artificial inteligence (capital I) but during exercise the actual word in A and small "l" (small L).
either remove those words or use this type words in meaning full words .
btw. you're doing Great work

Thank you very much for that note. You can change the font to "Courier New" under Settings - Training - Ticker. Then you can see the difference between capital "i" and small "l".
We will think about changing to that font for default.

All the best from Berlin,
