applicants should hold a bachelor's degree in aerospace, mechanical, or nuclear engineering (preferred), or in related fields like mathematics or physical sciences. A minimum GPA of 3.3 out of 4.0 is expected, especially in advanced mathematics and engineering courses. GRE scores are required, with preferred scores in the top 25th percentile for the quantitative and analytical writing sections. Applicants from non-engineering backgrounds may be admitted provisionally, subject to completing recommended undergraduate courses.
