Getting additional recommendation letters from other professors or highschool teachers?

Is it OK to get ‘additional’ recommendation letters from

  1. a professor who helped me with a high school research (but not a professor of the school that I am currently in)
  2. teacher who helped me a lot in highschool research (a director of a highschool club)

Thank you!

Yes, but they won’t carry as much weight as your college recs.
