Hello Dear Group;

I have a statistic course instructed on MOODLE learning management system.
most of the content in this course is coming from PDF.
in addition there are many Math symbols written on the web site.
Some of them just copy pasted from word.
I really need reliable updated links to read and learn how to make all the
content accessible for screen reader for my student.
