It’s the former. Even if mostly unsuccessful, so long as we see some evidence that you’re understanding, and attempting to follow our instructions, you’ll be good to move on. A lot of these things you won’t be able to improve overnight, after all. So, instead of grinding, simply give it another shot, and try to make use of what you’ve learned, is the concept behind the revisions. Looking at them now:

The superimposed lines look fantastic; smooth, properly lined up at the start, and of a consistent trajectory.

The ghosted planes are clean, and much better at not overshooting. Be careful to plot start/end points for all of their center lines, however- some seem to be missing them.

The rough perspective exercise looks better, in regards to its confidence, but the convergences themselves are unfortunately unchanged. Since the text instructions don’t seem to have helped, I’ll recommend something visual next. Take a look at this demonstration, and try to follow alongside it for a couple of boxes.

The organic perspective exercise is mostly improved, save for a misunderstanding. The points on the page shouldn’t just tell you the direction of the line, but its length, too. So, for the outer corners, the point of intersection should be a point, instead. That said, the boxes themselves look fine- you’re clearly planning them now.
