Have not been able to open any of Pset links, able to watch videos of lectures and shorts! any thoughts? Thanks
You can look up the problem sets (not the solutions, but the actual instructions) on Google. For example, looking up
Problem Set 1 C CS50 has the problem set link as the first result, which you can click on to see the instructions, walkthroughs, etc.
If you still have issues/comments, please comment below. :-)
