Hello everyone, thank you beforehand 
I just bought Premium like a week ago, because I was very interested on ussing the Difficult word button, that way I could practice the words that I had wrong on the normal review, but 
seems like it doensât work as I would like to, is this normal? explanation below:
Ok so, I donât want to add words manually to âdifficult wordsâ, I want the system to detect the words by itself but, this is what is happening. After I do a normal review and get a word wrong, the system adds it to difficult words, but right after then they highlight the Dificult word button for me to use it JUST after the normal review, so if the system is recommending me to use it, I will use it. But obviosly I will get it right because I just got it bad on the normal review and the word is fresh in my mind, and after I get it right 2 or 3 times in the difficult word section (usually its like 1 or 2 words only) then the system detect that I got it right 3 times in a row (if they are asking me the same word in a row obviosly I will get it right, will not?), and then they remove it from difficult words. I donât think this is effective or am I using it wrong???
I mean, they shouldnât remove the word from difficult words and keep asking it everyday or something like that, not remove it the same day the word became flagged as difficult.
Am I using it wrong? Is this normal?
thank you
