typo in "Verbs: Past Perfect"
if I am not mistaken there is a typo in the Tips and notes section of the lecture Verbs: Past Perfect ( https://www.duolingo.com/skill/sv/Verbs%3A-Past-Perfect ): At the end there is the sentence "All in all, past perfect in Swedish is very similar to past present. It is also used in the same way as in English." This is the first time I heard of the tense "past present". Probably present perfect was meant.
Please excuse me, if this is not the proper place to report this. The only alternative I found was to report a bug which seemed to be for technical issues (and would as such go to the developers instead of to the course maintainers).
