For the subdivision challenge, I probably subdivided too much, so I will delete the unnecessary edges before the final challenge of this section.
For the ramp challenge, I cheated a bit… Initially, I selected the edges and deleted them, but when I saw the holes that were left on the sides, I thought to myself: “This doesn’t seem right…”. And I then watched the whole video to see if there was a better solution and then I tried to mimic it. Hope, it’s ok for me to do that.
