Alejandro Arenas Teacher

I like to teach, my method is usually to build the concepts from each detail, seek to express everything in a simple way and try to be intuitive.
I focus a lot on the student's deficiencies, and I am in full track of his progress. I like to do practice exercises and assign tasks.
I am a person of great discipline, commitment, continuous improvement, with a great
sense of belonging, integral vision; I am a student in mathematics, and I going to finish
my bachelor in the first half of 2019. I worked teaching basic mathematics and physics to prepare highschool students for state exams. My greatest passion is share my knowledge, I am open-minded, patient and supportive towards other people.
