TESTIMONIALS

This was an example of how Mat 155 class should look like. Seff's teaching was perfect and students seemed ready and willing to learn from him. Mr. Seff first went over the homework from last class. The homework was about evaluation of functions at several points using simple programming in Maple, derivatives of functions and applications. Students enjoyed the presentation and it seems they are quickly learning Maple and also improving their knowledge in Calculus. The applications done in class helped students to understand better difficult concepts in Calculus like velocity, maximal height, tangent to a curve, comparison between a curve and its tangent etc. This was an impressive presentation of derivatives in Maple setup.

After the homework, Seff started a new lecture on increasing and decreasing functions. He went over comparison between a function and its derivative in Maple. After that students learned about applications to maxima and minima of functions, intervals of increasing and

decreasing etc.

Overall, David Seff gets my highest possible grade as an instructor 

“I am writing this letter so that you may be aware of how lucky you and your department are to have a such a womderful professor teaching math. Professor Seff has been a blessing to myself as well as to the other students in our 5.2 core class. The more professor Seff spoke, the more the more I began to think hey maybe I could do this after all. I can tell you that in a little over two weeks, my entire outlook on mathematics has drastically changed .”

​

“Professor Davide Seff was my math teacher. Never have I had a math teacher like Professor Seff. As a matter of fact, I've never met anyone  that thoroughly enjoyed mathematics like Professor Seff. He is so passionate about math that his passion comes through in his teaching. Perhaps if I had a teacher life Professor Seff years ago, I would have never developed math anxiety.”

“David Seff is one of the most amazing math instructors I know.  He has a firm grasp of many areas of math and the ability to articulate complex concepts in a way that students can understand.  His method of teaching is innovative in many ways.  One key part of his methodology is he explains important concepts by presenting slowly a well-chosen set of examples and stories that:

• Rely on simple ideas that are already well –understood by the students

• Make the concepts crystal clear

• Make the ideas so interesting that students actually comment out loud, “Hey this is really fun!”

• Use humor and get the students to laugh, thereby easing tension

• Motivate the students to listen, study, and understand.

By relating math laws and examples to everyday experiences, Mr. Seff is able to impart a deeper understanding of the material to the students as well as maintain their interest."

Dr. Seff was by far one of the best calculus tutors I have encountered over my college experience. With his patience and knowledge, he managed to help prepare me for my CLEP which I passed thanks to him. if you ever need help with Calculus I would recommend hiring him.

Professor Seff is patient and will do his best to help you understand material. I highly recommend him! 👍

Lucky to have found him!!! He is patient and thorough, highly recommend!

Mr. Seff is very knowledgeable about the subject, and very patient… and it was a pleasure working with him. If you are having problems and need a tutor for calculus Mr. Seff is the way to go. Thank you.

Our daughter loved working with Dr. Seff. In addition to helping her with the very demanding content of her Calculus course, he gave her confidence and was very generous with his time. After only a handful of sessions with Dr. Seff she felt great about her final exam! Two thumbs up!

Karl, father of high school student taking College Calculus in college

My son worked with Dr. Seff, whom we found did exceptional work. My son, a strong math student, graduated valedictorian of his class at a private high school and was accepted to a competitive engineering program at a prestigious university. We were shocked when he failed Calculus 2 at college. When he retook the class and only got a D, he was asked to leave the engineering program. He appealed and was allowed to stay on probation, thereby requiring him to retake the course and do well in it. We decided to hire Dr. Seff as a tutor at the beginning of the semester. The course was very intensive. There were approximately 30 homework assignments, often involving 10 or more difficult problems that were graded. There were also four midterms, weekly quizzes, and a final. Dr. Seff worked with my son about two hours a week. My son received a grade of 100 on every single homework assignment, A’s on all four tests (two of those grades being 100), nearly a 100 average on all the quizzes, and a 91 on the final. His cumulative average was over 95 (without a curve), and his final grade on the course was an A+! We are very grateful to Dr. Seff for making this happen. It was not just because of his math knowledge and his ability to explain things clearly, but also his patience, constant encouragement, and ability to identify the exact area of difficulty. We cannot recommend him highly enough.
