Organic Chemistry Tutor
I started my education career by tutoring students right after high school and into college receiving a BA in Chemistry. The request that I usually receive were hard core topics like Algebra, Geometry, Trigonometry, Precalculus, Calculus, General Chemistry, Physics, and Organic Chemistry.
Over time, I learned which teaching methods are most effective for helping students to not only understand the material but to retain it and to apply it during an exam to boost their score. Now, I focus more on creating videos and online courses that help not just students in my locality but students worldwide who might be struggling with this course.
Best Regards,

The way the teacher is explaining is very much understandable and with slow pace with basic things that helps in concept building.
By Anonymized User on 1/13/2023
The explanations are clear, the questions to solve are not too hard but are great to solve. this person is on youtube and when i saw this course, i knew i had to get it. in just 5 minutes I learned wonders. definitely recommend.

I used this course to guide me through Blitzer's Trigonometry 3rd edition. I read the section in the book, then watched the videos, and then did all the problems in the book. A wonderful course for a solid foundation on trig. Thank you Julio.
By Geraldine Cantwell on 10/15/2020
yes. when I get to the end I can tell you more.
By Ted Kollker on 10/13/2020
The basic of the course with good,
and it feels like the instructor is really trying to teach as deep as he can.
But,
sometimes there is a lack of explanation about the teaching topic, and I needed to try and understand it by myself.
Also (although it's rare, it still exists) sometimes there are mistakes in the instructor's calculation, and he is not corrected him self
