That "ing" at the end is a problem and makes the domain awkward. But you've got to work with what you've got. Better than a medical theme, I think, is this: Materials and assistance for people taking professional licensing exams.
There are plenty more, and your domain is better than most of them. If I were trying to sell this domain to one of those companies I'd approach them with a price of $4,500 and negotiate from there, with $3,000 as a target price but $1,500 absolute minimum. Remember, the real value of any domain name is the value to the end-user, not what some other domainer would pay for it.
