What are my chances for top notch schools?

<p>More info about GPA: All As during freshman year, 5 Bs and 2 As during sophomore, 1 B during junior. During sophomore year, academics just kind of lost its meaning to me because I discovered so many other hobbies. However, I realize its importance now and have improved my grade. Do you think it’ll help if I explain that on my college apps?</p>
