Hey Epitaph, welcome to the community! I'm one of the community members here and I'll be going over your work today so let's get started.

With your super imposed lines there is a lot of wobbling going on indicating that you are very consciously trying to guide the tip of your pen instead of executing a confident swift motion with your shoulder. At this point we are trying to teach students about the flow of a line. That is, the smoothness and confidence of it, rather than pure mechanical accuracy. So with this exercise it's all about trying to get those confident lines down on the page. Moving on to your ghosted lines, they are much more confident! They are swift, prioritizing flow over accuracy, and are drawn from the shoulder. There are times when you woble at the end trying to stop or hit the end point exactly, but instead of trying to stop try to lift your pen up as it is easier than fighting against the momentum of your arm and gives your lines a nice taper.

Moving on to your ellipses, overall they are shaped nicely and you're doing a good job drawing through them. Your ellipses in planes are making contact at the right spots on the planes, but in this exercise you get a little wild with the drawing through. Your tables of elliplses are good, and you do a good job keeping everything tightly packed so there's no ambiguity. Finally, looking at your funnels exercise you do a good job keeping your minor axes aligned toe the funnel axes, but here your ellipses get a little fuzzy with the drawing through, probably due to the added pressure of the extra constraint of the minor axes alignment. Overall good job though.

On your rough perspective boxes, you correctly oriented them by making sure your horizontal lines were parallel to the horizon and verticals perpendicular. Your converging lines are on the right track, and with time and practice your accuracy of lines going to distant points will increase. Your line quality is a bit shaky, as it seems you were more mindful of your lines than trusting the ghosting method and using your shoulder. This is common here as it is the first time students are asked to draw something besides an abstract exercise. Just remember to always use your shoulder and ghost and prep each line and you'll be fine.

Good job on completing the rotated box exercises! Your lines are confident and you do a good job keeping things neat in the midst of complexity. Your boxes are starting to rotate, but there's still a lot of shifting and skewing instead of rotating as explained here. Go ahead and give this gif another watch and really study how the motion of the vanishing points drives the rotation of the boxes now that you have some context. Regarding your corner boxes, you can see that they weren't really rotating, and you could have had more success if you had utlized the adjacent lines as perspective guides as explained in that link. Overall though this is definitely a hard exercise and you should not feel bad with your result as persevering through is more important.

Finally, let's look at your organic perspective. You've got good motion in these, and you do a good job overlapping your forms and scaling them down to both contribute to selling the illusion of 3d space on a 2d page. You are still doing a lot of line drawing over so try to work on not doing that. Your perspective is showing a lot of divergence (where the near planes are smaller than the far planes), but that's perfectly normal. I think the most successful fram is the third one on the first page as it really feels three dimensional!
