That’s a great point!
If you have grander visions for the model you are making (like using it as an asset in a game, not just simply making it and shooting some renders like in the course), you are certainly going to want to model it at proper scale. Modifiers may go haywire if you are modeling something at incredibly large or small scales, but you likely won’t run into this issue if you are modeling at a more accurate scale for the asset you are making.
An extra challenge if you aren’t too far into the course, you can try finding more accurate dimensions for a wand and take a stab at authoring your model closer to that! Be warned, the values that I use for the modifiers or transformations of the models will be far bigger than what you will likely need if you scale things down and work at that size.
