Can you update achievements after submitting UC applications?

Hey y’all

I’m a high school junior living in California, and I’m hoping to apply to either UC Berkeley or UCLA. In my sophomore year, I competed in the Academic Decathlon national championships, and I’m planning to do so again both this year and the year after that (knock on wood). Assuming that I’m able to make it my senior year, would I be able to update my UC application after doing that? I could probably expect an invitation in March of 2018, and I would be competing in late-April of that same year.

Thanks,
Thomas

Decisions will have been made by then. So/Ju year participation with an indication of plans to continue senior year is plenty of information.

Under “Years” list 11th and 12th - there is a place for this after the activity name and description.
