Once you have written your question bank, you can process it with LaTeX to preview your questions. When you are satisfied with your content, use the LaTeX to EDU conversion service to convert your LaTeX file into an EDU script.

In the first entry cell, you may either enter the absolute path to your LaTeX file, or press the first "Browse" button next to the cell to choose the file from a file browser. If you have a separate style file that you've used in your question bank, enter its path in the second entry cell. You do not need to upload ed.sty. The converter always has the current release of the ed.sty macros.
Click "Send File" to upload your file(s) for processing. A successful conversion will result in a screen similar to the following.

Click the "Click to Download File" link to download the EDU script to your computer. From there, you can upload the question bank to your class site.
If there is an error during conversion, you will be shown the conversion log to help you find the problem.
