I had very little acknowledge on accommodation when I was in college. I thought I just sign up and learn the way I'm used to. Sit there in class, study textbook, study the board. But the college counselor told me that she was assigning me to a different counselor because I'm deaf. I didn't know why at the time because I felt it would be pointless. But later found out this counselor had lay out all my options for me that I never heard of. Loops, notetaker, etc. I wasn't used to any of that stuffs. So therefore, I didn't fight for my needs. it was present right there for me. But I did have bad luck on notetaker because we had to have a volunteer in Class to do it, one woman offered to volunteer... but later after class, she told me she realize she didn't feel so confidence with her notetaking.
anyway, my point is, not everyone know what are their options. So some may never bother with accommodation.. or think it is all they have available. So we really shouldn't be blaming on the students for not fighting hard enough. We should be pointing at the counseling who was trained to handle these things.
