Art Institute instructors are very helpful and encouraging of questions. The best instructors are committed to displaying the most skills, creativity, inspiration, or knowledge about the subject matter that they teach. Students are informed every beginning of the quarter that the best way to contact their teacher is by email; instructors check their email frequently and answer questions promptly, so you're sure to get an answer to your question quickly.
The academic experience can be somewhat challenging. At first, it's relatively easy, as you become reacquainted with the basics, but then classes become harder, and you suddenly find that the material is more complex than you originally thought, as well as somewhat hard to work with. The challenging parts don't necessarily kick in right away, but academically, there are things about the school that are difficult.
