The admission board realizes that the first two years of high school, many students are still young and they don't see the importance of working very hard yet, but with time they realize it's time to focus. Which is why admission usually looks at your junior year grades, and if you had a few Cs you freshman and sophomore year, they could let that pass. But you have to make sure that you are on top of your game and continue to challenge yourself in athletics, ECs, leadership, and do not forget to take challenging classes, have a strong GPA and test scores. You can do it!!
