Starting with your lines, they do get better over the set, but are a bit wobbly.

In these exercises, you should always prioritize confidence over accuracy.

A wobbly line will always be worse than a confident line, no matter how off the confident line is.

If you take a look over the ghosted lines notes you'll see the levels of lines:

Level 1: Line is smooth and consistent without any visible wobbling, but doesn't quite pass through A or B, due to not following the right trajectory. It's a straight shot, but misses the mark a bit.

Level 2: Line is straight, smooth and consistent without any wobbling and maintains the correct trajectory. It does however either fall short or overshoot one or both points.

Level 3: Line is straight, smooth, consistent without any wobbling. It also starts right at one point and ends exactly at the other.

As you can see, wobbly lines aren't mentioned, which means that they would be worse than level 1.

Ellipses are pretty neat and confident in general, good job! On funnels remember that the minor axis should cut ellipses in even halves. Don't forget to aim for it.

Boxes look good overall, but they do have issues.

On rough perspective, you seem to have trouble keeping height lines perpendicular to the horizon line, and width lines parallel to it. I know it's hard, but be sure you are having it in mind.

On rotated boxes, some of your boxes weren't actually rotating, careful with that, this mistake is explained here.

On organic perspective I recommend doing more overlaps. You can clarify after the overlaps by adding a confident, drawn with the shoulder superimposed line on the part of the silhouette of the boxes that overlap. Perspective on them has issues but you'll work on it on the box challenge, so don't worry about it!
