ESL Robot 4.0 (Android Version) & (iOS Version) - an AI-powered English tutor

A: Hey, Professor Hill.

B: What is it?

A: I've been having trouble with derivatives.

B: That's not good. There's a test on derivatives next week.

A: I know. Can I make an appointment with you for some help?

B: I'm a busy man.

A: You didn't even check your schedule yet!

B: I know I'm busy, because many people already made appointments.

A: So I'm hopeless?

B: Of course not! There's the tutoring center.

A: But the tutors are not professors. They're just students.

B: They might surprise you.
