I am passionate about teaching students one-on-one, or in very small groups because I enjoy helping others and seeing how they get it. Therefore, your child will benefit not only from my knowledge base but also from my commitment to help you child to improve him/herself.

Currently I work as a mechanical engineer, but because I like tutoring so much I still tutor students on an individual basis.

Until Aug 2013 I worked for an year on a daily basis at A+ Tutoring Center, Westminster, as a math and physics teacher/tutor. There I helped students in grades VII-XII who are enrolled in courses ranging from prealgebra all the way to AP calculus BC or AP physics. Therefore, most likely I have seen the academic problems that your child struggles to master. I also taught a semester of SAT Math I & II at a tutoring center in Monterey Park during the Fall 2012 semester.

I have extensive experience, especially in the area of mathematics, where I can assist a student from middle school all the way to sophomore year of college. I dealt with all kinds of students, with different motivations: some needed homework help while others were falling behind and needed systematic help to pass. Most students I help just want the extra confidence in order to ace an upcoming quiz or test so that they can increase their grades. Whatever age or knowledge base your child has, I can help him/her to reach and exceed his/her academic potential.

I discovered my tutoring passion in high school when I took two optional peer-tutoring courses where I was aiding the math teachers in the process of teaching freshmen students. During my engineering program I took six advanced math courses at a university renowned for its math department. I also applied math and physics concepts throughout my undergraduate and engineering work experience. In my senior year I worked at my university as a tutor for first-year engineering students. I gained extensive one-on-one experience while providing them with math and physics help and aiding them in their transition process.

- Matrices and determinants
- Polynomials and polynomial functions
- Exponential and logarithmic functions
- Conic sections

I tutor on a daily basis AP Calculus AB students dealing with the following topics:

- Limits and Continuity (including L`Hopitale Rule)
- Rates of Change
- Explicit Differentiation Rules: (sum/difference, product/quotient, power, chain rule)
- Implicit Differentiation
- Applications of Differentiation
- Basic Antiderivatives
- Riemann Sums
- Trapezoidal, Rectangular Rule
- Fundamental Theorem of Calculus
- Average Function Value
- Substitution Method
- Trigonometric Integrals
- Partial Fractions
- Applications of Integrals: areas, volume, arc length, curvature, etc.

Differential Equations

I took two undergraduate courses pertaining to differential equations: Ordinary Differential Equations, and Partial Differential Equations.

The former course is the one I could offer my expertise on. The course started with the classification of differential equations (first/second order, linear/non-linear, constant/variable coefficients) and continued with solution methodologies for different types of ODEs and for systems of ODEs.

Solution strategies were presented for several types of ODE configurations. For first degree ODEs I learned the following strategies: separation of variable, substitutions of variable, Bernoulli DE, Exact DE

For second order DE I learned the following methods: fundamental sets of solution,complementary solutions for constant, homogeneous DEs, method of undetermined coefficients and of annihilators for constant, non-homogeneous DEs, method of variation of parameters and Euler's Method

I also learned how to combine the DE general solution with the given initial conditions in order to obtain specific solution. Application problems were from the areas of mechanical vibrations, flow, heat transfer, concentration, etc.

At the end of the course, I learned Laplace's transforms as an alternative for solving ODEs.


I master the following subjects in Geometry, and I teach them on a regular basis:

- Coordinate geometry: cartesian system, line equations
- Distance, length, and midpoint formula
- Angles, Lines and Points: definitions, parallel lines, angle relations in triangles and polygons
- Special Triangles: isosceles, equilateral
- Right Triangles: properties, Pythagora's theorem, introduction to SOHCAHTOA
- Solving Triangles: Sine and Cosine Law
- Congruency and Similitude proofs in Triangles
- Polygons: Parallelograms, Rectangles, Squares, Hexagons, regular polygons
- Circles: properties, formulas, equation
- 3D bodies: classification, properties, surface areas and volume formulas

Mechanical Engineering

I completed a Bachelor of Science in Mechanical Engineering within a co-op program, which means that I got to apply a lot of the concepts that I learned at school in real-world problems.

I am qualified to tutor in any Mechanical Engineering subjects because I completed numerous projects for each course, some on an individual basis and some on a collective basis. I received excellent marks and I am convinced that I can help any ME student to do the same. I also participated in numerous tutorial sessions, as each course had its assigned course tutorial taught by a PhD student.


I graduated mechanical engineering so I successfully completed the following courses:

- Physics I: Newton's Laws, Energy, Momentum, etc. for linear and rotation systems
- Physics II: Oscillatory Motion, Sound & Optics
- Dynamics: Newton's Laws applied to kinematics and kinetics for single particles and for rigid bodies. That includes linear and circular motion systems, linear and circular momentum and impulse, energy analysis
- Thermodynamics I/II: Conservation of mass, Conservation of Energy, 2nd Law of Thermodynamics, analysis of thermodynamics systems (plants, engines).


I have plenty of experience in tutoring precalculus, gained both from private tutoring and from my current employment. I master all the precalculus topics, such as:

- line equations and inequalities (including the ones with absolute values)
- cartesian system of coordinates
- functions: notation, domain, range, composition, transformations, inverse functions
- Polynomial functions and their simplification and graphing (quadratic, square root)
- Rational functions: evaluation and graphing
- Trigonometry: SOHCAHTOA, unit circle and CAST rule, trig identities and formulas, trig equations, parent graphs and transformations, data modelling
- Logs and exponent: notation and evaluation, simplification formulas, equations, applications (growth and decay)

SAT Math

I am currently teaching SAT I math at Academic Education Center, located in Moneterey Park. I use Barron's SAT I textbook, which includes all the topics on the SAT I test, including but not limited to:
- Arithmetic concepts such as fractions and decimals, ratios and proportions, averages
- Algebra I concepts such as equations and inequalities, polynomials, word problems
- Planar geometry concepts such as lines and angles, triangles, quadrilaterals and polygons, circles
- Solid geometry concepts such as volumes, surface areas of common solids
- Coordinate geometry concepts such as coordinate system, point coordinates, distance
- Functions and their graphs concepts such as line equation, slope, functional notation, function graphs and manipulations
- Counting and probability concepts, including arithmetic/geometric sequences, permutations and combinations.

In addition, I also tutor SAT II Math to individual students, where I cover more advanced concepts and their applications, such as Algebra II, Matrices and Determinants, Trigonometry, Pre-calculus, etc.


- Angle ratios (sin, cos, tan), their variations (csc, sec, cot) and their inverses
- Applications in right triangles and scalene triangles (sine and cosine law)
- CAST rule, reference and co-terminal angles, radians

Very good, detail oriented tutor that is easily accessible and flexible My daughter fell behind in her Honors PreCalc class due to an illness and she returned just 2 weeks before her midterm exam, so she needed help to catch up quickly. We were looking for a tutor that could jump right into the lessons that she missed and teach her the concepts quickly, thoroughly and with patience. Ioan exceeded her expectations, and therefore I would gladly recommend Ioan to anyon ...
