My flashcards keep repeating over and over again. Everytime I have closed the browser and start again, I get the same flashcards in the same sequence. These are not necessarily the ones that I need to practice (actually, I master them quite well, as I keep getting the same...). Is this a bug or the common way the system works?
I find that Flashcards aren't actually that useful because you can't choose the words/topics that you want to practise. I just strengthen the lessons again if I don't understand something or I think I'm getting a little rusty!
