Well, seems like the course creator does not have a forum account, so you can ask for @MemriseSupport to make you contributor, once you get the contributor status you will be able to fix the problem yourself.
Hi @electroblastz2, have your tried contacting existing contributor, @LanguageBox, who has put the following note in Level 1 of the course?
"LYoudale unfortunately hasn’t been active for some time, so this course has suffered a severe lack of care and attention recently. The people up high have granted me contributor access to this course, which means if you have any vocab levels you want adding, any words you want editing or any queries whatsoever, you can now contact me, LanguageBox, on the Memrise form (see the link at the end of this message).
I have tried getting in touch with @LanguageBox but to no avail as they have not used the forums since October 2019.
That’s why I thought it would be convenient for me to obtain contributor role since I am much more active on the site and know which errors in the course need to be fixed (as mentioned in my recent post).
Based on their recent track record, I expect that the Memrise team will likely add you as a contributor within about 10 days.
I took a look at this course recently, but because noun genders are included in parentheses after each noun, one of its weaknesses is that learning genders may be difficult. There are arguably better GCSE German Memrise courses available, but most are based on AQA rather than EdExcel syllabuses.
Having said that, it might be worth looking at some other courses, which appear to have similar coverage and are of very good quality, for example:
*AQA GCSE German - by immyjenn - Memrise
I took a quick look through the course and, in case it helps, here are some possible typos I’ve noticed. I’m guessing you’re aware of most of them already.
