Is the braille used in the app and on the graphics UEB or Nemeth within UEB?

If your student is using refreshable braille with the iPad all material is in UEB. Most of the graphics are in UEB with numbers in the upper part of the cell as per BANA guidelines for technical material with whole numbers. Graphics, including tables, that have fractions, decimals etc. have been prepared both in UEB and Nemeth within UEB context so that you can select the format that your student is familiar with using.
