There are pros and cons to applying by November or December to qualify for an early decision. The best option is to research early decision and early action to learn if that is the best choice for you. Early decision is binding and will require you to withdraw your other college applications if you are accepted. If you are not sure, it is best to select early action or regular decision, either of which are not binding. Early decision is best for students who know exactly where they want to go. You also won't know your financial aid package until you're accepted. If you're still considering your options, you may not want to lock into a school just yet.
