Applying to college

When i submitted my uc app I put my legal name from my social security. The problem is that I noticed on my high school, my name is almost the same, but it is missing a letter before my last name, which is part of it. What should I do about this? Thanks. ( I applied to ucla, UC Irvine, UCSB and UC Riverside.)

call each school and let them know of the discrepancy.
