Yea i used nearly all of my time, sometimes stopping it short by 15 seconds or so. I think about time limits as a reflection of how in-depth they want your answers to be, similar to secondaries. You probably had short and long secondaries on the same question (ex. diversity). In that case your answers aren't fundamentally different, but you'd use more examples and be more descriptive with the longer ones. It's the same with VITA.
Additionally, once you incorporate stories and anecdotes to back up your responses, it won't seem like a long limit. Try it out on a practice test first.
Edit- woops I realized this post is old. Oh well lol
