* Rigor of your coursework: Did you take the most challenging courses available at your high school? AP, IB, and honors classes are crucial.
* Standardized test scores (SAT/ACT): High scores are generally expected, though some are now test-optional.
* Extracurricular activities: Demonstrating leadership, passion, and commitment through involvement in clubs, sports, volunteer work, etc., is essential.
* Essays and letters of recommendation: These provide insight into your personality, character, and achievements beyond academics.
* Talent and unique qualities: Do you have any exceptional skills or talents? Are you a nationally ranked athlete, a published writer, a renowned musician, etc.? Uniqueness is valued.
In short, a strong upward trend in GPA is a positive factor, but it's just one piece of a very complex admissions puzzle. A 3.3 freshman year might raise some questions, but the subsequent 4.0s show improvement and dedication. However, you'll need a compelling application in all other areas to have a realistic shot at an Ivy League school.
