By the way, can someone tell me the difference between "znát" and "vědět"?
Read here https://www.duolingo.com/comment/26487658
Gees, I got both "Jeste" and "nevim" wrong. THAT takes talent!
Can i use " už nevím "
No, you can't. I tried to explain the difference between ještě and už here https://www.duolingo.com/comment/26862763 but not very well I am afraid.
As I unserstand, už is like a "yet" that you will use in affirmative questions and ještě is used in negative statements, right?
Something like that.
Thanks for your help, it is really helpful for a beginner like me
Can one say "Ještě neznám"? I checked the link, and somehow I feel this might be acceptable - in certain contexts maybe?
No, not without an object.
