One of the difficult facts of life is that when you are applying for work is that no matter how skilled or brilliant you are in your field, the first filter employers use is certifications. Going back to university (or any educational institution) is a big ask for someone with severe tinnitus. I want to know if universities (even online), etc allow students to be tested at their own availability. I'm fearful of going to an examination or being tested while having a tinnitus spike. Also, are there strict timelines for handing in assignments?
