How could a writer best revise the above sentence to avoid overly formal language? cassidy does not know which course she will register for. cassidy does not know for which course she will choose to register. cassidy does not know for what course she will register.

The correct option is “Cassidy does not know which course she will register for.”

This option avoids long grammar structures and makes it easier to read.

The other two options are too wordy and use clauses that do not add meaning to the sentence.  

So the first option is better to avoid the overuse of formal language.

Cassidy does not know which course she will register for.

This is the best way to revise the sentence to avoid overly formal language. It is the one that is the closest to everyday speech. Sometimes when trying to create something less formal it is best to think about how you might hear it said among friends in a lunchroom. It is very rare for a student with his/her friends to say "for which course" or "for what course" unless it is a fragmented question. These are not common phrases found in less formal English.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
