I also need to think about common pitfalls students might have. For example, confusing the Galois group with the automorphism group in non-Galois extensions. Or mistakes in computing splitting fields when roots aren't all in the same field extension. Also, verifying separability can be tricky. In fields of characteristic zero, everything is separable, but in characteristic p, you have to check for inseparable extensions.
