The assignments are graded by humans and, therefore, are not immune to mistakes, so of course you can approach us if you feel like we missed something.
Feel free to open a new discussion in the forum describing what is unclear or approach us after the tutorials (not as safe as posting to the forum as we can't guarantee there will be enough time afterwards).
