I am czech by nationality... rather confident in my english, so.. I am learning other languages.

Mainly the following four:
Portuguese
Russian
German
and Italian

... however I try some others too.

Moreover I am using Memrise to Memorise Chemistry and some anatomy.

I believe chemistry courses are underfeatured and underestimated here ... they have much better potential ... and maybe I will create one to my teste (already collecting material for it)
