The right answer is "A) You will have more time then to do a careful job."
Summer, before senior year, is the perfect time before the chaos of September rolls around for you to start the preliminary phases of college admissions. Schedule tour visits for any college campuses that you have not yet visited and make notes that can be used to eventually narrow down your choices. Start considering which of your teachers would write a strong letter of recommendation. Take time to look over the Common Application and begin brainstorming some topics that you could use for your personal essay or personal statement. Once you narrow down your choices, explore their websites to learn admissions requirements and request an application. Make sure that your senior class schedule will meet all of the required courses you'll need for enrollment.
