PRESIDENT GRANT CURRENCY
This may sound crazy, but trust me, its not. Start talking about your reasons, about your life, what you are passionate about and many other things, but talk – really – speak out load, slowly, make small comic remarks, add a little color to your sentences and personal comments about decisions and certain periods in your life. Talk while you drive, while you take a shower, while walking to school or walking your dog, before going to sleep… while watching a boring TV show, the important thing is to let it out and listen to how you sound, how IT sounds, because this is the way its going to sound the day of your college interview. And for this you better prepare.
Practice answering tough, directed questions about your experience, motivation and goals, be prepared to draw colorations between your experience and what seems to be the need of the institution. For example, if you are applying to a course that requires strong analytical skills, you should have example ready to demonstrate your strong analytical skills. Some questions may involve topic like college admissions, be prepared for that too (research college admissions).
