He's a fantastic teacher who goes above and beyond to help his students succeed on the ICAO exam."
Guilherme Henrique Porcincula Coelho

I would like to thank Professor Ricardo for all his attention and dedication, not only focusing on passing the exam but also on what we can actually encounter in real-world situations. ICO will always have my recommendation! Thank you to the entire team and especially to Professor Ricardo Siqueira. See you in 2030."
Caio Bauer

My first SDEA/ICAO test, I was happy to reach level 4, getting very close to my goal (ICAO5). I will continue studying and improving more and more to achieve it. I thank Ricardo Siqueira for all the support and teaching."
Vinicius Buchina

In my opinion, he's a great professor who is really focused on teaching for the ICAO exam! His pronunciation is easy to understand, and his explanations are very clear. I've already recommended him to several friends, who I'm sure will feel much more confident about the exam after taking his classes!"
