Homeschool

Calculus,

Calculus

I have a BS degree in Math, graduating with honors. I started tutoring Calculus while in College, and I've been successful helping my students connect with the material and becoming successful.
Precalculus,

Precalculus

Precalculus is a key subject in the High School curriculum which formalizes and extends many of the concepts in previous courses and adds new ones that will serve as a bridge to later courses. This makes Precalc a particularly challenging subject for many students, and at the same time it makes it a specially important one, as it lays the foundation for the more advanced concepts and procedures routinely used in Calculus. I have extensive experience tutoring PreCalculus to students of all levels, and my ability to make the concepts in the Precalculus curriculum understandable to any student by following different approaches is one of the reasons that sets me apart. I have been helping students succeed in Precalc for many years, let me help you as well!
SAT Math,

SAT Math

I have been helping students improve their SAT Mathematics scores for many years. SAT Math uses concepts that are not particularly challenging, but because students are likely to not have seen some of the specific types of problems in the SAT Math exam most are likely not to score up to their full potential. I will help you practice, reason, and fully understand all the types of problems you will be tested on in your SAT Mathematics exam so you can be confident that when exam day comes you will be prepared to do well.

Trigonometry is a fundamental part of the curriculum that teach concepts which will be used throughout the later High School and College years. The concepts involved in Trig are simple, and if applied systematically, they allow the student to build a strong foundation. Let me used my extensive experience in Trigonometry and Precalculus to help you succeed!

Great Tutor!

Ruben was great! We will continue with his tutoring for sure. He has the students best interest, is very flexible and makes himself available outside of the tutoring as well. Very helpful!

Amazing Instructor

Ruben is not tutoring my child in Calc AB he is teaching it. My daughter works with Ruben twice a week. He is an excellent instructor. Incredibly thorough- sends her extra practice, etc.

Knowledgeable & patient teacher

Ruben is a great teacher. He takes a methodical approach with the student to set them to success. We have been taking tutoring lessons for Algebra 2, now AP statistics and SAT math. I can’t thank Ruben enough for making my kid feel more confident on the concepts and encouraging him to do more practice. Thanks Ruben!

Well prepared

Ruben is the sort of tutor who comes in very well prepared and expects his students to do the same. I am hoping this will help my son get more organized and learn better. We have had only two lessons and they seemed to have gone well.

Organized and Excellent ACT Math Tutor!

My son waited to almost the last minute to start thinking about preparing to take the ACT for the second time. After much convincing, my son agreed to get a math tutor to prepare him for the ACT in two weeks. Ruben S. agreed to help him. Ruben was able to break down complex equations in an easy to understand format. He was always organized and prepared for each session with great follow up. My son met with him online for a total of 6 - 1 hour sessions. I’m happy to report that we just received my son’s new ACT scores. His math score went up 4 points in just those two weeks of tutoring with Ruben (composite score up 3 points). Thank you, Ruben!

Extremely knowledgeable

Ruben is very knowledgeable and passionate. His tutoring techniques are customized based on the needs of my child. He also provides a very detail summary of the tutoring session afterwards.

thorough and patient

I am taking a calculus class after a long absence from mathematics, and Ruben has been phenomenal in exploring where there are gaps in my knowledge, and addressing those gaps.
