400 words of TOFEL Intermediate English course

Dear Memrise
I am writing to notify about mistakes that I have observed in " 400 words of TOFEL Intermediate English course" .

Firstly , I have found this mistake, " nobility" was meant " a group of socially and politicially prominent." Politicially is wrong and the correct spell is politically .

Secondly , I have found this mistake. subtly was meant " in barely noticable way". Noticable is wrong and the corret spell is noticeable.

Naturally , I am using Memrise and I am learning English so it is better that Memrise will be perfect .

Your faithfully
