About Khoi

I am an energetic, thoughtful, dedicated instructor who designs his own lesson plan for any field of math and science for any age. My fourteen years of experience in teaching college students at the University of California, Berkeley, have prepared me to teach motivated minds and see them succeed. My past students have gone on to be doctors, lawyers, and even teachers like myself. My method of choice for tutoring is hands on one on one tutoring with the students doing active learning where they are applying what they learn to real life situations. They can apply this knowledge so that they can see future applications. I find that this method helps them visualize future skill sets where they would find joy doing a certain job. I have also taught in a huge classroom setting and I find that it is a necessary skill to learn in a large group format so that you do not get lost in the crowd. I always encourage students to ask as many questions as possible and do my best to always provide them with a thoughtful answer. In time, I hope to be a trusted friend and compatriot who will provide life long advice to my fellow students.

Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.


I have lived breathed and played basketball my whole life. I have played organized basketball since grade school and have been a leader on the court and have always coached my teammates as a point guard. I was heavily recruited coming out of high school, but turned the opportunity down because I wanted to further my studies as an engineer. My credentials are that I played 2 years of high school basketball at Oak Grove High School. We won our division both years that I played and made it to the final of the CCS championships the last year that I played. To this day, I use my knowledge of biomechanics to help players improve their game and learn better techniques to improve shooting, dribbling, and defense.


As an active instructor of Physics and General Chemistry for over 10 years at the Berkeley Review (MCAT Preparatory center), I am well versed on this testing manner. Along with my background in Bioengineering, I am well versed to teach the Biological Sciences. My qualifications comes from my score of 36T(PS 13; VR 10; BS 13, WS T)to teach this subject matter.

For physics, I can teach all topics from translational motion to light and optics.
- Translation Motion(vector/scalar notation, breaking vectors into components, trig review, simple kinematic equations, graph analysis of x vs t; v vs t; a vs t, projectile motion, and range)
- Force, Motion, Gravitation(Newton's laws, force problem recipe, statics and dynamics problem analysis, test taking tips, gravitational force, uniform circular motion, rotational kinetics)
- Work and Energy(Work=Fparallel*d, PE(gravitational and elastic), KE, work-energy theorem, heat energy(Q=mCpT), Hooke's Law, Conservation of Energy, Power)
- Torque and Momentum(t=Fperpendicular*lever arm, equilibrium problems, moment of inertia, momentum, conservation of momentum, collisions(elastic/inelastic), angular momentum)

- Sound & Doppler(longitudinal wave, wave of pressure/displacement variation, speed of sound in different mediums, sound intensity, intensity level, resonance, closed pipe system, open pipe system, beat frequency, Doppler Effect)
- Fluids and Solids(hydrostatic pressure vs total pressure, Pascal's Principle, Archimedes' principle, viscous fluid flow, laminar vs turbulent flow, Poiseuille's Principle, Reynold's Number, Continuity law, Bernoulli's Equation, Young's modulus, Shear modulus, Bulk modulus)
- Electrostatics & Electromagnetism( Coulomb's law, electric fields, dielectrics, induced dipole, work=electric PE, electric potential, magnetic fields, right hand rule, magnetic force, mass spec.)
- Electric Circuits(conductors, insulators, resistance, ohm's law, energy from battery, power dissipation, Kirchoff's Loop and Junction Rule, resistors in series/parallel, capacitors in series/parallel, capacitance, RC circuits)
- Light and Optics(EM spectrum, speed of light, energy of light, doppler shift, index of refraction, polarization, dispersion, law of reflection, snell's law, total internal reflectance, thin lens and mirror equation, plane mirror, convex/concave mirror, convex/concave lens, images are UV or IR, myopia, hyperopia, converging and diverging devices, young's double slit experiment, thin film interference)

Each one of these above is a two hour class that I teach for the Berkeley Review.

For General Chemistry, I have taught everything from electron theory, VSEPR, and periodic trends to Thermochemistry.
- Electron Theory, VSEPR, periodic trends(s, p,d,f orbitals, electron configuration, Pauli's exclusion principle, Hund's Rule, Aufbau Principle, quantum number, periodic trends, Zeffective, VSEPR Theory, emitted color vs reflected color, color wheel, photoelectric effect)

- Thermochemistry & Thermodynamics(energy diagrams, exergonic, endergonic, enthalpy, Hess' law, heat of formation, bond energies, calorimetry, heat transfer(convection, conduction, radiation, evaporation), heat engines(carnot cycle, heat pumps, heat engine)

I have specifically taught each of the above courses in general chemistry.

For biological sciences, I can teach anatomy, physiology, biochemistry, immunology, genetics, and neurology.

For Writing Sample, I received T on my MCAT and know how to break a prompt down to the x-factor and have a paragraph for the pros and one paragraph for the cons to handle the normative statement from the prompt.

I give Khoi A+ in communication! 100% for the tutor time! Plus extra credit for his approach! — My first impression of Khoi was his friendly picture and his helpful write up on the WyzAnt website. He kept communication up through email and phone whenever I had a question or change of plans. At one point, before our first session, Khoi took the time to check in with me about all the details and lesson plans of each teacher. I really liked how he was willing to be prepared before he came. He a ...
