COSMOS vs. SIP

Hi CC, I’m a high school sophomore looking for some guidance. I have a few questions:

  1. Is COSMOS or SIP harder to get into?
  2. Which program has greater weight in future college/summer program applications, and which would look better when looking for internships at local universities (feel free to include any other reasons why one program is superior to the other)?
  3. COSMOS has a deadline of April 6th 5 PM PST for acceptance, but SIP releases decisions on April 6th… does SIP historically release decisions in the morning or early afternoon? Do you think this is cutting it a bit close?
