I've been doing Duolingo for awhile and have been pretty good at retaining the information and completing the Legendaries. A couple of months ago it updated as it has many times. It recalibrated my progress and removed my legendaries for past lessons. Totally understand, but the issue is that when I go back to do them, I don't know the words or constructions they're testing me on. Doing the reviews barely works because they cover only a tiny part of what the Legendary will test me on. Sometimes I'll do a review for a "past" lesson three or four times and I won't be able to get through the Legendary version at all. I'd like to go through the original lessons again, but I don't see an option for that.

Does anyone have any advice? It makes me not want to do Duolingo anymore because I can't learn what it expects me to already know.

Edit: Thank you for all your help, guess I'm going back and resetting. It'll be helpful to have the course based on my current knowledge.

I have this denim jacket that is starting to fray at the edges so I'm thinking of doing a satin stitch hem to protect them. I recognize that the fraying is part of the aesthetic but I thought it might be cute to do a rainbow trim and good practice. I don't have a lot of experience with sewing/mending: a few patches/buttons, a little cross-stitch, only used a running or backstitch so far.

What do I need to do this by hand? And is this a good idea/waste of time?

I would do the collar, front placket/button stand?, and cuffs. I feel like I would need a ton of a thread, potentially embroidery thread would make it go faster. I have needles, but with denim I'm wondering if a sashiko needle would be better.

This feels like a fun project over the summer but I'm worried that I'm under prepared. Thank you for the advice!
