Hello @Almark.L and welcome to the forums!
No, this shouldn’t be much of a problem. Usually, Memrise will realize that you’ve already learned that word. However, since this is a pretty comprehensive course, I’ve removed the entry in level 75 now.
Thanks for reporting this!
Thanks for creating this great course.
I was wondering if learning these words helps with the IELTS or TOEFL exam as well?
Or should I take a more specified course?
Hi @narges_sh and welcome to the forum!
No, the course has no reference to IELTS or TOEFL. Most of the vocab contained is well beyond C2, so I doubt that you’d see much of it in official tests. But that is my personal assumption - I am not the course’s creator but rather took it over as the author is no longer around. I thus have no idea about the author’s original intention.
That said, I’d recommend to look for a better match. Here’s a search for IELTS-courses and here’s a search for TOEFL-courses.
Thank you for the help 
hi, I’m using your course to refresh my English.
“if the shoe was on the other foot”
I don’t think it means “if I were in your place”, that would be “If I were in your shoes”.
“if the shoe was on the other foot” means “if the situation was completely reversed”.

Good find, @acnalbasac, cheers!
I have now changed this to “said when a situation has been reversed completely (usually to the worse)”.
