Here's why it's difficult:
* Overall GPA: Harvard calculates your cumulative GPA. Even a stellar performance in your junior and senior years might not raise your GPA enough to be competitive with applicants who consistently performed well throughout high school.
* Trend: While improvement shows resilience, Harvard wants to see consistent high achievement. A sudden jump can raise questions about consistency and long-term academic potential.
* Rigor of Courses: The courses you took during your first two years also matter. If you took less challenging classes initially and only increased rigor later, it might not fully compensate for the lower grades.
* Explaining the Discrepancy: You'll need to convincingly explain the reason for the initial poor performance in your application essays. A compelling explanation (e.g., documented learning disability addressed, family circumstances significantly impacting studies, etc.) is crucial but not a guarantee of admission.
In short, it's not impossible, but extremely difficult. While a strong finish is a positive factor, it needs to be accompanied by other compelling aspects of your application, including:
* Exceptional SAT/ACT scores: Top scores are nearly essential.
* Strong extracurricular activities: Demonstrated leadership, significant achievements, and passion are crucial.
* Compelling essays: Your essays need to show maturity, reflection, and a clear path forward.
* Strong letters of recommendation: Teachers and counselors who can attest to your significant improvement and potential are vital.
Focus on making the most of your remaining time in high school, but be realistic about your chances. Harvard admission is a highly selective process. Consider applying to a range of colleges, including some that are a good fit for your profile even if your chances at Harvard are slim.
