Your tutor remembers what you already asked.

You ask the tutor a question. It answers. You ask a follow-up. Instead of starting fresh, the tutor knows what you've already talked about in that lesson.

It's a small thing that makes a huge difference. You're not re-explaining concepts or losing the thread. You pick up where you left off.

The conversation stays focused on that one lesson, so the tutor stays focused on what you're learning right then. No wandering into unrelated stuff.
