Transfer tips

Hi everyone,
I am going to be graduating high school and felt that I have preformed terrible. I have unweighted HS gpa of 3.3 and a weighted of around 3.7 I have not checked but I am pretty sure cause I have only taken honors and AP classes, took 8 AP class rank of 513 out of 753, have a few extracurricular activities such as Varsity Lacrosse, and as a Volunteer at Children’s HealthCare. I just want to ask any tips or information on how to succeed in order to reach a school of your dreams. I understand that for many a college that has a name is not worth the cost, but for me I have failed early in my high school career and I am trying to use that has a guiding tool and motivation to succeed now and when I graduate high school. I have a large list of schools mostly the top 50 schools in the US. I just wanted to start a thread so people can give out advice and lessons learned from both failures and success.
