Once you have figured out a general subject area such as physics, you should brainstorm more specific topics by putting pen to paper. You can’t write about WWII because that would be a book's worth of material.
What was your favorite chapter you learned in that class? You don’t want to write about what type of soup prisoners of war received in POW camps because you probably can’t come up with 4000 words on it.
The key here is that the comparison needs to be significant.
I compared two plays to show a transition in British Theatre.
In layman’s terms, my IB Diploma was graded during May 2010, I wrote my Extended Essay in the English A1 category, and I received a grade A. We combine world-class expert tutors with our proprietary teaching techniques.
Our students have gotten A's on thousands of classes, perfect 5's on AP tests, and ludicrously high SAT Subject Test scores.
If you're really stuck trying to find a not too broad or narrow topic, I recommend trying to brainstorm a topic that uses a comparison.
Once you begin looking through the list of sample essays below, you may notice that many use comparisons.
Make sure you ask your IB coordinator if there is any required paperwork. If your school needs a Form signed, make sure you bring it with you when you ask a teacher to be your EE advisor.
Note: The IBO only allows advisors to suggest improvements to the EE, but they may not be engaged in writing the EE.
