Ghosted lines are p confident but you have some wobble issues in the superimposed lines:

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.

Same goes for ellipses, you got a few wobbly ones, so focus on getting them confident. It doesn't matter if the accuracy falls off. I recommend to draw through them only 2 times as well.

Boxes are good overall outside the major mistake you're doing, which is repeating lines when they're off:

No matter how off a line is, don't repeat it, keep going as if it was correct.

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