Many people agonize over choosing an area to emphasize.
Each area has specific rules on how to complete the emphasis correctly. Only you can decide which emphasis is best for you. It all depends on your interests, strengths and weaknesses. For example, if your ultimate goal is to go to law school, it would make sense to emphasize any of the areas. If you want to improve your writing and presentation skills, Area I - Communication, Language and Literature would be an excellent choice.
