Short units with the graded details built in: the n − 1, the bonus tolerance, the even number of Simpson panels.
Fresh problems every time, with hints and full worked solutions.
Timed practice exams, graded instantly, with the units to review.
Each track opens with a review of what you need from earlier classes.
Six tracks.
Each one maps to the courses that grade it. Take them alongside the class, or before it starts.
Measurement & Lab Skills
Units, measurement statistics, uncertainty propagation, curve fitting, sensors and sampling, lab reports.
Drawings, Tolerances & GD&T
Orthographic and section views, dimensioning, limits and fits, tolerance stack-ups, GD&T and bonus tolerance, fully defined CAD sketches.
Numerical Methods
Error and convergence, root finding, numerical integration and differentiation, Euler and Runge–Kutta, iterative linear solvers.
MATLAB Programming
Arrays and indexing, control flow, functions, debugging, cell arrays and structures, file I/O, plotting. Problems ask what the code outputs, like the exams.
Arduino
LEDs and resistors, breadboards, binary, PWM, analogRead and the serial monitor, pots, if statements and loops, RGB LEDs and buzzers, ultrasonic and temperature sensors, servos and motors. Topic order follows Paul McWhorter’s Arduino series.
C++ for Engineers
Types and integer division, formatted I/O, selection and loops, functions and references, arrays, strings, pointers, classes, file I/O and numerical methods. Problems ask what the code prints, like the exams.
