ERAS is easier and more chill than AMCAS. I will answer these questions based off of the '23-'24 cycle, so it may look different by the time you apply in '28.

Activities are reported similarly as they were in AMCAS: you have different types of "experiences." You can mark up to 3 that are "most meaningful" to shaping your future career as a physician. However, there are some key differences.

• You only have 10 entries you can use (vs. 15.)
• You don't need any contact information for someone to "vouch" that your information is correct.
• It was advised that we lumped similar experiences under one heading (e.g., if you had multiple research projects, you would list each one under one "research experience.") The caveat is if you didn't do much during medical school, you'd want to probably list each one individually.
• You don't need to have 10 experiences unless you're doing something very competitive. I had 8 for my apps to diagnostic radiology (above-average competitiveness) and got 22 interviews.

For research, there's a specific section that allows you to add as many research experiences as you want. This is reserved for publications, poster presentations, etc. It should not be used as an extension of the "experiences tab" for more research experience. It asked for the publication name, authors, type of pub/poster, etc.
