Kaafi pointless tha. I tried it for German which I knew the basics of.
Doesn’t teach you phrases you use in life but more structural stuff that you may learn in a course.
Also makes it easy so you feel like you know stuff but you may not actually be able to use it in the country that actually uses the language natively for conversations or to follow what they are saying. For that, movies with subs help a lot more.
I tried Russian and did manage to learn the alphabet mostly, so credit where credit is due!
