Cheri,
Unfortunately, it appears that the picture you tried to share is too large for Ask an Expert to handle. Can you upload a smaller resolution picture?
I cannot respond to your specific material without seeing it.
Nonetheless, generally, within an uncontracted environment the only thing that needs grade 1 mode is lowercase letters a-j that follow unspaced after a number (because otherwise such letters read as digits; e.g., 123 #abc versus 12c #ab;c). Without contractions (i.e., in an uncontracted environment), other symbols cannot be misread (because they can’t be read as contractions since none are used anywhere).
I hope this helps, and I look forward to seeing your specific material.
