Darwin had several interesting pieces queued up for the lesson. He did a totally awesome job preparing for this lesson, guiding me, asking me questions about the material. I was really impressed and it is an honor to be able to learn with Darwin.

Had a great discussion with Darwin! He was patient with my Spanish and helped me when I couldn't remember words. Highly recommend!

Seriously Darwin is one of the best tutors I've ever interacted with. I think he is the 40th person I've talked with on iTalki and he is one of the best. Very calm, he is super attentive to my questions. I feel like my pronunciation is making leaps in improvements with him. I'd say I'm an intermediate-advanced learner and he is perfect for my level. His accent is also super neutral. He always prepares lessons in advance and they are usually spot on with things I have to work on. I would recommend him to anyway, really great tutor.

Darwin's lessons are well organized and he is a very patient teacher. He provides plenty of encouragement and allows me to learn at my own pace. I highly recommend him to the Italki community.

I enjoy taking classes with Darwin. He is very patient and kind. He always comes prepared and has material for me to study. Looking forward to more classes with him.

I've taken 270+ lessons on italk.com. I'm working towards taking the C1 DELE exam. Darwin is the best teacher I've encountered on here. He is motivating and actually very, very good at teaching grammatical structure. Would recommend to anyone, I think he is going to get me where I need to be for C1.
