my name is Paulo and I'm taking cs50 through edx. I noticed that the pset0 and the pset1 used to be at week 0 and at week 1, respectively. But for some reason, now they are at week 1 and week 2, respectively. I thought that was a mistake of mine, but during the classes of week 2, David Malan mentions the pset2. So now I'm wondering if there was a mistake in edx and pset0, 1, and 2, correspond to week 0, 1, and 2, respectively.
Since there is less psets than weeks, could someone tell me which week matches each problem set? I have searched for it but I can't find it.
