I am a rising junior and I attend a top 30 Liberal Arts college. I am double majoring in Math and Economics and my cumulative GPA is 3.75. I have worked as a research assistant for two summers and I should be able to get really good recommendations from both the professors that I worked for. I will be applying for either the Winter or the Winter + Spring semester/ trimester. Provided that one meets the 3.6 minimum GPA cutoff for the visiting student program, how tough is it to get in?
