It was good
Very good explanations and amazing notes! Only problem is that the microphone quality is low, but that doesn't really matter.
Very helpful and efficient tutor, he helped me study and revise the mathematical part of Quantitative Method 3 with optimization, integration, and dynamic models. I would recommend him to anyone struggling with algebra or geometry.
Very helpful!
Great last class. Andres has been fantastic. Thank you for all your help. Definitely recommend working with Andres to all other students.
Great class. Andres helped me complete 2 more questions. I now understand how to do a for loop and reshape the data in R which I couldn't do before.
Extremely helpful.
Helped me work through my problem very effectively.
Andres is an excellent tutor for my daughter. He has helped her prepare for Math Olimpiade and also with school work. Her math skills increased considerably. Thank you Andres! - Inong
Strongly recommend! Comes prepared and is very pedagogical. Helped a lot in explaining Discrete math topics :) - Joseph
