About David A.

Subjects

Algebra, Calculus, Pre-Calculus

Education

Bachelors in Engineering, General from Universidad Nacional de Colombia

Career Experience

When I first started studying biological engineering, I discovered how truly passionate I feel about calculus and math in general. I always excelled in my classes, but sadly as I graduted, I realized that biological engineering was not the major I wanted to make my life about. I've never been afraid of starting over, so I decided to go back to university and, by the next semester, I will be starting to pursue a degree in computer science.

I Love Tutoring Because

tutoring has taught me a lot of new approaches and techniques to solve problems I wasn't aware of. I love tutoring because there's no better feeling than knowing the positive impact you are creating in students who are seeking for help, and they genuinely appreciate it. Tutoring has also helped me improve and keep up to date with all the necessary knowledge for my future courses!

Other Interests

Archery, Book collecting, Computer programming, Creative writing, Digital arts, Paintball, Swimming, Traveling, Urban exploration, Video Gaming, Volleyball, Weightlifting, Writing

It wasn't anything the site or the tutor failed to do, but seems my issues may have been more software related than material related. Overall it was a good experience though.

David, once again, has made the course material easily understood and digested. helping me through the problem without doing it for me but supporting me in such a way that i can find answers for myself and understand how. Thank you David! ill pass this class because of your help!

I believe myself to be a relatively harsh critic when it comes to tutors on this site. That being said, I could not possibly have higher praise For David and his ability to thoughtfully but quickly and effectively help me through the problems I had today. His willingness to stick with me and guide me through difficulties in the course material and allow me the time and space I needed to form my own thoughts is exemplary and should be studied by most of the rest of your tutors who have a tendency to shy away from 'giving out answers' so much so that they hinder students interested in reverse engineering answers to understand the process. Thank you David, for understanding that im not here to just get the answers and run, and teaching me more in 2 hours than ive been able to learn from my textbook in 2 weeks. 10/10 stars. I will be returning to this service and it is because of tutors like David.

I was hesitant to conduct a one on one tutoring session because I have never done it before. David was amazing. He didnt feed me answers, but guided my thought process to come to conclusion and verified when I was on the right track or needing to rethink the work. I truly appreciate the time given.
