I have been teaching engineering classes since I was in University. I experienced how difficult was to not find help anywhere, so I decided to help people in several areas of engineering. Being struggling in Academia is such a bad experience, so I always try to encourage my students to keep working hard and seeing their problems as a way to be better every day. I am always looking for new methods, techniques, and methodologies to help my students. There is always a chance to make studying fun and easy and my main goal is to help as much as I can.
I'm graduating this term form my Bsc in mechanical engineering and I won the ELAP scholarship where I had the chance to be in Canada as part of an exchange program at the University of Saskatchewan for an academic year.
I have 3 years of experience in tutoring as part of my university mentor's program and students in research groups.
It is a pleasure for me to find these resources to expand my possibilities to help people around the world.
