Our experience with Alexis was absolutely outstanding. My son was struggling with a higher-end math course in college, necessary for his curriculum, and laboring with a less-than-ideal professor. My son began sessions a few weeks into the semester, and they prevented what would otherwise have been a disaster. Alexis is a truly gifted individual, with an uncanny natural mathematical ability combined with the rare talent of being able to convey complex ideas in a manner that makes them accessible and understandable by the student. Additionally, Alexis is personable, punctual, meticulous in responding to contacts, and very easy to talk to. Should my son encounter difficulties in future courses, I know where we will turn. I would heartily recommend him as a Class-A, top-of-the-line tutor.

Shila, 8 lessons with Alexis

Alexis has done a great job this semester helping my son with Algebra 1. He brings such a deep understanding of math that he is not just helping my son get through the class. Alexis sets him up to really understand the concepts so that he can succeed in later math classes. Heartily recommend working with Alexis to any student seriously interested in deepening their understanding of the subject!

I have had tutors here on Wyzant for many years with good results. Alexis is the best there has ever been!

Helen, 11 lessons with Alexis

Alexis was a great tutor and helped me with Assembly. I came on the 4th week of classes with barely any understanding of the course material. In an hour and a half, Alexis patiently explained all the material to me to the point where I feel very caught up. There was no time wasted and we went straight into the material. Alexis had a great feel for when I understood something and would go on from that subject and would only go over the material that I needed help. In 1.5 hours I went from thinking that I would fail the course to thinking that I was in the top 10% of the class in my understanding. I would recommend Alexis to anyone who is having problems with assembly, computer architecture, Risc-V and any course material that he covers. Definitely the best tutor I've ever had. I wish every professor was like him. I will definitely come back for more lessons.

Christina, 18 lessons with Alexis

I’ve went through multiple tutors and Alexis is the most patient with me. I’m not the smartest but Alexis is so kind and understands so much.

Antoine, 4 lessons with Alexis

Not only was Alexis a great help when it came to the material itself (Assembly Code ARMv8), but he also looked up very helpful material on the subject. In addition, he provided more comprehensive reviews on professor-made solutions that seemed to be drawing from many different styles of coding, pointing out where there were less efficient ways of coding and how to improve upon the answers. Essentially not stopping at the right answer, but WHY and HOW it could be improved. Would highly recommend!
