Ruben S. Wyzant

“You will not find a more dedicated, professional tutor than Ruben. Not only is he an extremely talented mathematician, but he is also an exceptionally caring instructor. Ruben provided tutoring services for my son in Pre-Calc and Calculus and helped him achieve very good grades at a demanding college prep high school. I only wish that my son’s high school teachers were as thorough, exceptional, and reliable as Ruben was. Despite his very busy schedule, Ruben never let us down. He has an incredible work ethic and, having used other tutors in the past, I can unequivocally state that he is one of the best tutors you will ever hire.”

— Catherine, 77 lessons with Ruben

“Our son's AP Calc teacher reached out to us late in his senior semester that our son was just barely passing. As we are busy parents, there was not much time left, as we desperately sought a tutor for our son on this topic. Ruben's profile came up as a top choice, and we reached out -- Ruben responded within minutes and we scheduled our first session for our son in a matter of days. Prior to our son's first session, Ruben reached out proactively and inquired about areas where our son needed help and provided ample preparation material for him. Their first session went swimmingly well, and likewise, subsequent sessions were equally as successful. Our son was well equipped and wound up scoring near perfect on his next test! Our son put in a lot of work himself, and Ruben was very supportive providing ample study materials, and reaching out before and after every session. Ruben is definitely best of breed in this field and we highly recommend him.”

— Peter, 6 lessons with Ruben

“Ruben agreed to take a big responsibility to teach concepts of both Calculus AB and BC in a fast paced manner in only 3 months which is a monumental task. Ruben has been very flexible in with respect to scheduling and also with adjusting pace, practice vs teaching, and stepping in for subjects not part of the initial class schedule. Also, he has been able to balance student and parent's preferences and kept the student engaged with such a rigorous class and pace!”

— Revati, 18 lessons with Ruben

“My son has always struggled in math. He worked hard at learning it but it did not come easy. While pursuing his Welding AS at Las Positas, it was necessary to pass Trigonometry. Since he did not take Algebra 2 in high school, this seemed like an insurmountable task. Fast forward to us hiring Ruben S. as my son's tutor. Ruben is reliable, calm, encouraging and supportive. He worked with my son twice a week throughout the semester. My son completed and passed the course and now has his AS in Welding. Ruben S. not only helped him pass but also improved his self confidence. He is a phenomenal tutor and I highly recommend him.”

— Lisa, 28 lessons with Ruben

“We are incredibly grateful to have found Ruben to help our daughter catch up in her Calculus BC class after she fell behind due to illness. In less than two months, Ruben’s expert guidance and support made a remarkable difference- our daughter was able to catch up and do well on her exams. Ruben’s deep knowledge of Calculus BC is matched by his efficiency and dedication as a tutor. He consistently kept us updated on our daughter’s progress and always sent detailed lesson notes after each session, which was extremely helpful. Ruben was encouraging and supportive, going above and beyond by reviewing material and answering questions even outside of scheduled lessons. His friendly demeanor and excellent communication skills made every interaction a positive experience. Having worked with many tutors over the years, we can confidently say that Ruben stands out as the best. We highly recommend him to any family seeking outstanding math support!”

— Michael, 42 lessons with Ruben

“We started the class with Ruben in early July. Before this, my daughter struggled a lot with her maths not only because she didn't catch up well at school but also because she didn't build good learning habits. she cannot finish homework, and it is very hard for her to concentrate. very lucky we chose Ruben as her tutor. everything changed slowly now. Ruben teaches her maths but also encourages her and helps her with learning habits and building confidence. everything changes now and as parents, we are really appreciated. Ruben told us it is a long way to help kids build up good learning habits but he will stand aside us to support! He is not only a good teacher but also knows kids very well. He is a real educator !! thanks Ruben”

— Anna, 15 lessons with Ruben

“I’m extremely grateful to have had Mr. Ruben as my AP Calc AB teacher this year. With his expert knowledge and help, I’ve become much more confident in understanding difficult concepts in Calculus. He made sure that I grasped each concept very well, put in extra time whenever needed, and helped me patiently with any topics that I struggled with. He promptly replied to any questions that I had in between my weekly classes with him. Notably, Mr. Ruben isn’t only an amazing teacher, but he’s also a really kind person. He’s such a great motivator and has been as much invested in my learning and success as I am myself. Going forward, I know I can count on his help even as I start my undergrad at UC Berkeley this fall. I highly recommend Mr. Ruben to any student who’s looking for a knowledgeable, kind, and supportive math teacher. Tvisha Ranjan”

“Ruben has been my son’s Calculus tutor for the past two years now. He’s helped him with Honors pre-calculus and currently, AP Calc AB. He’s really helped my son understand the material, empowering him to achieve excellent grades in both math classes. I personally appreciate how organized and detail oriented he is in his lesson summaries and notes. He’s always there to answer questions for my son if he has a test the next day and has a last minute question. I would highly recommend Ruben as your advanced math tutor.”

— Amy, 39 lessons with Ruben

“Ruben tutored my daughter for 2.5 years, from precalculus through AP Calc BC! She received almost all A’s and is now attending a Texas A&M as an engineering major! I cannot say enough about his professionalism. Ruben is always prepared and always goes the extra mile for his students! Very knowledgeable and a gifted instructor. She could always understand a difficult construct after Ruben explained it and he was always there to provide additional practice. I highly recommend him!”

— Robin, 109 lessons with Ruben

“Ruben has been teaching my son Precalc for the last one month. He is very thoughtful, responsive and a great teacher. He follows up, provides notes, and always checks in between the classes on how he is doing. He is willing to help and provide support and gives great tips. I would highly recommend Ruben !!!”

— Junita, 5 lessons with Ruben

“As my tutor in various subjects, Ruben has gone above and beyond in providing great teaching services. I initially started learning with him before the pandemic studying in person before transitioning to online classes. My experience with online classes with Ruben has been excellent, the best online tutoring I’ve had with any tutor! I definitely think it is at least equivalent to learning in person. Ruben is a very kind and honest person that likes to help people. He is extremely trustworthy and reliable, so much so that my tutoring experience with him has lasted more than three years! I highly recommend classes with Ruben. My experience of studying with him has gone through many different time periods and schedule changes, but he has always been flexible and willing to accommodate me wherever I am living and whenever I am available to study. He also always gives feedback on the major things we learn in our lessons and makes sure to provide notes to students afterwards so they are always keeping track of their progress. Ruben also does a great job of allowing students to learn freely while also correcting their mistakes when necessary. His classes have always gone very smoothly, and Ruben is willing to make adjustments to the learning plan based on student feedback. I think Ruben is a great tutor and I highly recommend his tutoring services!”

— William, 217 lessons with Ruben

“Ruben has been helping my sixteen year old son with Trigonometry. He is very smart and knowledgeable, but what is also very helpful in our case is how supportive and encouraging Ruben has been. My son can tend to be a bit self-negative and feel like math is just not his thing and shut down a bit. Ruben continues to assure him that he can tell he does have a strong aptitude for math, and if my son will put in the extra time and practice with math even on his own in between tutoring sessions, his math skills will strengthen as will his confidence in his own abilities to do math. In the last two weeks he has received As on his last two Trig quizzes and is very proud and really starting to see that he can do it, and the extra time spent studying and practicing really does help! This is a LIFE lesson! So thankful to have Ruben in our lives for this valuable help!”

He was extremely helpful. Completing the course as fast possible was very important to me. Without Ruben this wouldn’t have been possible. He went above and beyond and was very flexible. Ruben is an amazing tutor! Highly recommend.”

“Ruben has worked with both of my children preparing them for their SATs. I can not recommend him enough. We have used several tutors via the Wyzant app and all have been excellent. Ruben, however, takes it to the next level. He is professional, highly skilled and motivated for his students to excel and do their very best. After every lesson he sends notes and provides feedback on their progress. One of the best things about Ruben is that both my kids liked and respected him and that made the process very easy. I highly recommend him.”

— Catherine, 64 lessons with Ruben

“Ruben took on our high schooler at a critical time. Our son has struggled with math since he was little and it's his Achilles heel. First, Ruben is insanely patient. I am sure I would have fired my son as a client:) He continued to support our son to work harder, gave him tips for weekly study practices that created deeper understanding. He wrote out problems for our son to work on in between their meetings and went over material when our son, sadly, did not do his practice problems as planned. Again- very patient man. Ruben is OUTRAGEOUSLY communicative in the most timely fashion. He corresponded with me and kept me in the loop. We coordinated for him to chat with the math professor so that all channels of support were aligned. My son hated the math:)....but loved working with Ruben. We have 5 sons and have needed help for each across various subjects. I can confidently say that Ruben is a fabulously unique tutor. He is insanely knowledgable in his subject, but marries that with a genuine care for his students and a lovely personality to boot. Stop looking- your kid will do better in math with his help.”

“Ruben is a very capable mathematician. Beyond that, as a teacher, he is patient, accommodating and way more than willing to go the extra mile.

Thanks Ruben!”

“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!”

His attention to detail, precision, and knowledge of C++ (and other programming languages) proved extremely useful. Additionally, Ruben is punctual and dedicated, and he really seems to enjoy teaching. I could not have asked for a better instructor to introduce me to a field that was completely new to me!
