Knowledgeable and patient tutor
"I was struggling with linear programming HW, so I scheduled a tutor session with Archie. It went very well. He knows the concept of linear programming very well and did a pretty good job of explaining it. Highly recommended and I will definitely schedule for future sessions with him."

"Archie was a great help to my frustrated freshman high school daughter at High School who broke down the Algebra 2 lesson to explain it so she could understand and learn. Her math teacher is a very poor teacher and only made her more confused. Archie took the time to find out her problems in advance to be prepared for her lesson. We will use him weekly. We are very grateful for helping her and highly recommend him."

"Dr. Medrano is a great tutor. He helped my daughter to get an A in Calculus III when she was in high school. Patience is a virtue and Dr. Medrano is the epitome of that adage. Also, he is very skillful in explaining the problem for her. I would recommend him to anyone who is in need of help in mathematics."

"I was in desperate need of a tutor for the SAT. I contacted Archie and got a respond really fast and set up a meeting for the same week. I met with Archie every Friday for 3 hours until the SAT. I hadn't taken math in a year so I really needed help. I learned so much in our tutoring sessions. He explained everything very clear and made sure I understood what he was doing. I highly recommend Archie."

"I've had one session with Archie so far and it was amazing. We discussed Discrete Mathematics and Linear Algebra. He put me a week ahead on the syllabus. Even though I was ill-prepared and late he was really nice about it (and HE was punctual). I can tell if he's not familiar with material he will research it and explain it to you. Since he's an instructor, he has a lot of great study tips too, and has experience with the things that work to help students learn. I asked him the same question a dozen times (more than once) and he was completely patient about it. He was so effective in explaining that I sort of ran out of things to ask about. Free tutors at school are nice to have, but there is a lot of value in having a private tutor like Archie just for you, who has experience and will remain patient if you're struggling. I am hoping to meet with him regularly and really looking forward to a much better GPA this quarter!"

"I had a 3 week survey of calculus 130 class at USD and I didn't know how to do at least half of the material. I met with Archie the day before my final (worth half of my grade) and studied with him for 4 hours. He was very flexible and answered all of my questions concisely and intuitively. I got an 86 on the final which saved my grade. Recommended."

"Archie is the best thing that happened to my academic career. I have worked with Archie starting with Calculus 2 moving through Applied Math for Engineers which covers both Differential Equations and Linear Algebra. I am yet to see a single question fluster him. He has slowly turned a deer in the headlights when it comes to math to a Mathematics minor in University and I will will always keep him as a reference whenever I run into a problem. To shed light on my situation when I met Archie, I was a repeat math student of a lower division math class and have come to be able to excel in all my math classes. The more time you can afford to work with him the more drastic the results you will see. I highly recommend him for any subject and he is fantastic at filling the holes in your previous math knowledge whenever they appear. Thank you Archie!"

"Archie tutors my high school sophomore in Algebra2/Trig. My son says that Archie is very patient and makes difficult concepts easy to understand. Archie is very flexible with his scheduling and more importantly, very responsive! My son texted him late one night with a question (his math test was the next day), and Archie responded with an answer even though it was pretty late. I highly recommend Archie if your student needs math tutoring."

"I cannot recommend Archie enough! He is an extremely patient tutor and is always willing to explain something again if you don't understand. I've had him explain a concept to me that I was struggling with several times and he never got frustrated or impatient. He actually wanted to make sure I got all my questions answered and even had me do some practice problems after to make sure I fully understood the concept. He is an excellent teacher and I think he would be good for any level. He is also very punctual and very flexible in terms of scheduling."

"If it wasn't for Archie, I would have failed the course. Archie is understanding of his student's needs. It was well worth my money. Thanks again."

"Hello. I am a current student at the University of San Diego. I am studying Mechanical Engineering as a major and Math as a minor. I would say that the math courses at USD are very rigorous and demanding, but Archie has had a significant impact on my performance in the math courses here, such as Calculus II, Calculus III, and Applied Mathematics for Science and Engineering I, the last two of which I am currently in now. When sitting in class, it is sometimes hard to understand the concepts, but Archie goes into depth and explains them from a different view than my teachers do. This allows me to see it in more than one way. He also goes over things he believes you should know for the class such as Trig Identities, which really do help and come in handy. Overall, I would say that he is the best math tutor I have had and is at a great and reasonable price compared to other tutors. I would recommend him over any other tutor."

"Archie is punctual, patient, knowledgeable, and always ready to explain anything you throw at him! I am a Calculus student at UC San Diego, and he's very flexible with scheduling and is able to meet on campus for students! Also has very affordable rates available, and is very patient in explaining math. Archie rocks!"

"Archie was an excellent tutor. He was willing to work around my schedule and set times that worked for me, and gave me advanced notice if he ever needed to change the plans. He was very friendly and easy to work with. He was also able to explain the concepts to me better than my teacher could, which was very helpful. My only regret is not hiring him sooner."

Great Tutor
"Archie was very easy to work with from the get go. He responded the same day by email, and we were able to meet 4 days later. I had set up a meeting for help with the CBEST test. He was very prompt and prepared. I had a series of math problems ready for review, and he was patient when going over them. Make sure you know what subjects and/or material you need help with beforehand, or it's hard for any tutor to help cover the entire course prep. He explains the problems in detail, and helps you along the way. I would suggest Archie for anyone that is as bad in math as I am!"

Balance of Explanation and Figuring it out.
"Archie was great! He gave me enough time to try to figure out a problem by myself then would step in to guide me through the process if I couldn't get it. He knew what he was doing so there was no confusion when he was explaining the material. He was also super easy to schedule with."

Confidence inspiring and very patient.
"I have always felt trapped by mathematics and I have always approached it fearfully and without much excitement. Yet, when it comes time for my sessions with Archie, I find myself getting excited to go through my GMAT preparation knowing that I'll have the support of a knowledgeable, qualified tutor who not only has the educational background to breeze through my GMAT studies, but, more importantly, has the personality necessary to listen and learn how I am thinking and then proceed to teach me based on my own personal learning style. Archie is steadfast in his philosophy and his performance is the most consistent I have experienced and I have worked with numerous tutors over the years. Furthermore, whenever I am scheduling meeting times with Archie, he makes me feel as though I am his priority and that he is dedicated to do what is necessary for me to get past my troubles with math. He works with me until we have reached our goal for the day. As a student who is working towards a goal of taking the GMAT, it is important for me to feel as if my goals (not the tutor's) for the session have been met and with Archie, that is always the case. (On a side note: I rarely invite tutors into my home and after meeting with Archie only a few times, I felt comfortable inviting him in my family's house. He has been nothing but respectful and trust inspiring)."

"I have had the pleasure of working with Archie for almost 10 years. He is a pleasure to work with: very conscientious and has excellent analytic and problem solving skills. When my oldest son needed some help with his AP calculus (BC) studies in high school, Archie agreed to help with some tutoring sessions. The sessions were very helpful and my son ended up with an A in the class. Two years later, my younger son was in the same situation (AP Calculus AB) and, again, Archie was able to help. Both boys have left for college, one at UCSB (Bio-psychology) and the other at CalPoly (Engineering). Archie knows his stuff and was a great help."

Fun and an amazing tutor!
"Archie is one of the best tutors I have ever had. He makes tough trigonometric proofs so simple and special right triangles a breeze. Archie not only helps you with subjects you may be struggling in, but also gives you a glimpse of what the SATs are. He gave me my first ever "A" in geometry, the subject I have been struggling most on. I look forward to meeting him every time we make an appointment. He's a wonderful tutor and makes each session a blast."

"I have asked Archie to tutor my daughter (high school student) on numerous occasions. He helped her with Discrete Math and Geometry and I was impressed by his knowledge in the subjects. I also liked that he was very patient. He was also able to teach my daughter how to figure out the math problems without giving her the answers, which helped her think more by analyzing the problems. He also helped her with SAT subject test in math. I highly recommend Archie for any math tutoring need."

"Archie tutored me during all stages of mathematics for my Bachelors Degree in Engineering. His teaching technique was in such a way where I was challenged and guided into finding the solutions myself. He quickly understood my strengths and weaknesses. He then would derive questions and challenges for me to gain greater understanding of the topic at hand. Archie is a great tutor who helped me achieve an average of >80% for my mathematics subjects during my studies."
