This is an old post, so I don't know if you'll see this, but I hope you don't give up on your daughter's college plans. My son just graduated last week with a bachelor's degree and he's severely dyslexic. He was able to go to college with accommodations - such as speech-to-text software, textbooks on audio, and extra time for tests. Most of his professors were quite understanding when he explained his issues. We had to take him to a neuro-psychologist for an evaluation to qualify for accommodations at the college. It was expensive but worth every penny. When my son reach his mid-teens I felt a lot of responsibility and shame for his lack of reading and writing skills, but much of it was due to his dyslexia - something neither one of us could change.
As for Trail Guide to Learning, we used it for three years and absolutely loved it.
