Starting with your form intersections, these are by and large coming along quite well specifically in the construction of solid forms and the definition of clear relationships between them. I do however want to draw attention to the fact that you went back over each and every form's outline with a darker stroke, specifically in the manner explained to be incorrect here.

Continuing onto your object constructions, your work here is by and large quite well done. Your constructions show a great deal of patience and care in applying subdivisions to establish specific positioning for each and every form, and as a result, that specificity allows for a considerable degree of solidity to the constructions themselves. Even those with a lot of ellipses and rounded forms like the tea cup and spray bottle came out very nicely.

The first issue I want to point out is actually the same as what I remarked upon in your form intersections: no cleanup passes. In the instructions for lesson 6, specifically where you're allowed to use a ballpoint pen, I mentioned:

Ballpoint pen for your linework (don't switch pens to do any sort of "clean-up" pass - use the same pen through all your lines, including construction/box subdivision/etc)

Line weight should have been added with the same kind of pen - a ballpoint in this case - so as to avoid the issue where we end up tracing back over all of our lines. Line weight should only be added as a way to clarify specific overlaps, not to completely separate the "final drawing" from the forest of lines. Specifically the behaviour we want to avoid here is the tendency to trace over linework, which tends to focus too much on the lines as they exist on the page, rather than the 3D edges we're meant to follow. We can see this in cases like the tea cup (whose raw construction on the left is considerably stronger as a result than the somewhat less even and chunkier result on the right side). It's not that going back over your marks is wrong as a general rule - just that we don't want to get into it in this course, and that above all I want to stress the importance of understanding your construction as it exists in 3D space at all times. Any action that focuses on the final presentation of the drawing, at the expense of understanding it in 3D space, is counter-productive for an exercise like this.

With that out of the way, as I mentioned already, your constructions are very solid. The only one that seemed noticeably off was the fruit bowl, which admittedly from looking at your cross-sections was quite complicated. The box you started out with does appear to be a little bit skewed to start, which didn't start you off on a great path, and due to the complexity of the orthographics, I definitely would have opted for much tighter and more specific subdivision. You weren't shy in doing this for your other drawings - the mug for instance was loaded with subdivision, but here your curves appeared to rely a lot more on eyeballing rather than specifics. As explained here, curves are vague in their very nature, and in order to provide the structure for a solid construction, they need to be supported by much more specific underlying plans.

Anyway, aside from those points, I think your work throughout this lesson is very well done. I'll go ahead and mark this lesson as complete.
