The course will not let me use contractions.

In the course you can write your answers using the full forms of the verbs (I am) or the contractions (I’m). You must use an apostrophe (‘) to write the contractions. If you use an accent (´ or `) in the contractions, the course will not accept the answer. Check on your country’s keyboard where the apostrophe key is.
