Final answer:
U.S. graduate institutes consider GPA, extracurricular activities, standardized test scores (GRE, GMAT), personal statements, interviews, and letters of recommendation to evaluate the aptitude of applicants.
Step-by-step explanation:
Graduate institutes in the US evaluate the aptitude of applying candidates using a combination of various criteria. While a candidate's GPA and extracurricular activities might provide a broad look at their educational performance and personal interests, standardized test scores such as the GRE or GMAT offer insights into their general aptitude and readiness for graduate-level studies. Personal statements and interviews are crucial for understanding an applicant's motivations and interpersonal skills. Lastly, letters of recommendation offer an external perspective on the candidate's abilities and character. These evaluations are akin to an employer's method of vetting potential employees by assessing their academic performance, accolades, and references to gauge hard work and ability.
