What classes offer the best opportunities?

@justonedad, the thing is my closest friends are taking the exact same courses, and they have better GPA’s and grades. They also seem to want to attend the exact same colleges I wish to attend. As of now, I want to study neurobiology, and I have been looking into Ivy League schools. My school offers a Statistics class for senior year. I haven’t yet, but I am going to begin to volunteer at places such as hospitals and other places too. I also golf for my school’s team, if that has any important meaning.
