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!
I would try strengthening individual skills. You know that all the word strenthening will be from that skill.
Never do a general strengthen if you have any weak skills. Always do a skill-specific one instead. Only do a general strengthen if all the skills available to you are gold.
