Charles - Know your tutor

My name is Charles Oji and I have two degrees from MIT. Each degree is in "Electrical Engineering and Computer Science". My GPA for undergrad is 4.2/5.0 and 4.6/5.0 for grad school. And I have won several awards including getting the US Green Card under the special category of "Alien of Extraordinary Ability". 5 years later, I became a US Citizen. In July of 2024, I was inducted into the invitation-only, prestigious and honorable "Who's Who in America" group that is run by the 125+ year old "Marquis Who's Who". I have been teaching for over 15 years and I have taught over 8,000 students and professionals. I am a Senior Software Engineer by profession and I have been approved as an Adjunct Professor at Alabama A&M University and Calhoun Community College. I have worked at companies and organizations like Capital One Bank, JP Morgan Chase Bank, Discover Financial Services (DFS), Goldman Sachs and the United Nations (UN). My teaching experience includes over 42 subjects in 7 areas. These subjects include Computer Science (Software Engineering, Java, C#, HTML, SQL, Computer Networks), Math (Algebra, Calculus, Trigonometry, Linear Algebra, Differential Equations, Discrete Math), Software Engineering, Physics, Electrical Engineering, Chemistry and Test-Prep subjects like the SATs, PSATs, ACTs, the Regents, GRE, ASVAB, TOEFL and the GMAT. Last but not least, I am very punctual, very organized, hard working but easy-going. In addition, I make my lessons fun. So connect with me so that we can learn something cool together. I look forward to working with you. Happy Learning, Charles Oji.

Student and Tutor reviewed vector operations, including unit vectors and finding terminal/initial points, and confirmed the Student's understanding of the midpoint formula. They practiced applying the section formula for points dividing a segment in a given ratio and solved a system of three linear equations using both elimination and matrix inverse methods. The Student plans to complete outstanding lab problems and practice questions from the textbook to solidify their understanding before the next session on Friday.

Solving Systems of Linear Equations: Matrix Method

Vector Operations: Unit Vectors & Points on Segments

Midpoint and Section Formulas for Vector Segments

Solving Systems of Linear Equations: Elimination Method

Matrices: Determinants and Inverse of 3x3
