What do you like best?
It is professionally structured and exam invigilators (at least the few that i had) were very resourceful when it came to assisting in anyway possible
What do you dislike?
It is hard to say what I dislike about OnVue, but if I had to find something it would be that for some finding the correct section for what you are trying to do may be a bit difficult. Not impossible but it does require you to stop for a second and make sure you are going to the right section.
What problems are you solving with the product? What benefits have you realized?
OnVue has helped me with my test taking anxiety and helped me to realize that test are more straight forward than you believe (Must also be prepared for the test).
