It’s really hard to say since we are all different. I agree 150% with @Fyrius on this one, and will add that if you manage to frustrate or annoy him too much, he may take that as a lesson akin to finding out that putting your hand on a hot stove may cause painful injuries and never learn anything from you even if you change your methods and start doing everything right.
The only thing that can really be said with certainty is that the boy has a very different thought process than you do, has at least as hard a time of getting through to you as you do getting through to him (if not harder, depending on his linguistic ability), and is probably frustrated in general due to being surrounded by a bunch of “aliens”.
Regarding the thought process, imagine you are a small child playing in the kitchen. You cut your hand with a knife that has a red handle. Most kids would take that and turn it into a fear of knives, but an autistic kid may well draw a different association and grow up to be afraid of red things, or of kitchens.
My anecdote from the other side has to do with my two years of Freshman English in high school. The first time was with a by-the-book teacher and went badly enough to require taking the course again. The same class with a teacher that actually understood and cared that I was a little different took more of a hands-off approach and guided me more than taught me, and I had a 92 average.
