Repetition in "Strengthen skills" mode
I'm doing the "Strengthen skills" mode twice a day but for almost a week Duolingo has been repeating the same kinds of lessons (V.Inf. 1 and V. Inf. 2) even though my skill level for these lessons is still strong. It gets really annoying because it is very repetitive, and especially because the skill levels for the other lessons keep dropping. Anyone else with a similiar problem? Thanks!
