do you think i should start somewhere else and than learn Hungarian using duolingo or vice-versa?
I would say that if you really want to learn Hungarian, you should start with Duolingo first, as Duolingo can teach you basics, and quite a few sentences. After Duolingo, I'd go to Memrize, and after a bit of Memrize learning, I'd go on to a more Intermediate Hungarian learning website. I wish you luck with your Hungarian learning if you decide to go through with it. ;-)
My opinion is that you should start somewhere else, because this particular course is too irritating even for people who have some experience in Hungarian. Try to get a good coursebook or grammar book, and some simple texts. You can return here anytime if you want some equilibristics which does not have much in common with actual learning.
