Is it too late for me to use Crimson Education as my guide to stand out in Harvard University admissions application

I really want to strengthen my grades and maybe add an AP also because my high school does not provide any, I feel as if though my dream cannot be a reality, my grades are low, GPA is low, I am not a leader in my school, I do have an extracurricular which is my school’s ECO club but I do not think it is enough to get me to an IVY League University such as Harvard
I need Crimson’s help to achieve my goal, or to make my dream a reality.
