Retakes should be allowed
I've been on outlier for three months now (math). I improved a lot both in terms of my knowledge of math and how to task on the platform. Thinking back about the first project assessment I had, which I obviously failed because I had no idea what I was doing. If I take another assessment for this project again I would likely pass it, but it seems that I'm permanently "unmatched" to it.
I think outlier should invest in allowing retakes after some time because we also learn along the process. That also means they have to make new assessments for the same project but so what? it's a little investment that can improve everyone's experience.
