Strengthening Swedish: repetitive?
I am working on my Swedish, thank you for setting up this great website! Now I am running into a problem though: while learning, everything seems fine, many different sentences pop up. But when strengthening skills, I get 4-5 sentences all over again until close to the end, where some new sentences come in. I would appreciate this if it were hard sentences that I failed at in the past, but that does not seem to be the case. Is there some mechanic at work that I do not understand?
Thanks and cheers!
