Depends whether you actually NEED the help or not?
If not, then sometimes better not to mention it.
I recently enrolled for a (short) OU course. During the enrolment, they asked if I had any "special needs" they ought to be aware of.
Thinking that a relapse might strike at any time, and cause me to miss an assignment or something, I thought it best to mention up-front that I have MS, as that would be more plausible than only raising it when I'm about to miss a deadline - or have already done so.
So anyway...the result? I get a great big form to fill in about "my needs", and a list of all the "help" that is available - none of which applies to me or I'd qualify for.
I read that "in no circumstances" will an extension be granted to coursework, so it's a complete waste of time having told them I've a tendency to get ill without warning. It will be tough luck if that happens.
So I wish I'd never mentioned it at all. Got a load of useless bureaucracy to fill in, none of which I can be bothered with - and with a deadline of three weeks.
Now getting reminders about "We still haven't heard from you about your needs". I'm not doing it! There aren't any needs they can help with anyway. I just wanted it on record I was ill, in case I should start struggling with the course.
Should have kept my mouth shut!
