The notes she has from the teacher ARE her notes pursuant to her IEP. She should be allowed to use them in any way other students use their notes. If all other students are allowed to use their notes for a test, she should be allowed to use her teacher-provided notes. Since you're short on time, I would reach out to the entire IEP team asking for assistance. If you don't hear back quickly, reach out (maybe call) the director of special education. If you have a phone call (or calls) make sure to write everything down that was said.
