Please specify the full name of the high school or program you're interested in. For example, is it:
* A school with "OSA" in its name? (e.g., [School Name] OSA Academy)
* A program within a high school called OSA? (e.g., [High School Name]'s OSA program)
* Something else entirely?
Once you provide the full name, I can help you find the admissions requirements and application process.
