Educake accepts spelling mistakes, like any teacher would. And just like any teacher, it then shows the student the correct spelling of the answer, so they can improve.
If a student spells a word really wrong, then they won’t get the mark. Here are some examples of correct and incorrect answers. For example, if the answer is ‘nucleus’, things like neucleus, nuclues, and nucleis would get the mark. Things like neculas won’t. The rule is that answers can have up to two characters that are wrong (different or missing).
