Full university-level courses with infinite practice problems, step-by-step explanations, and interactive simulations. Free forever.
Core Engineering
The foundational engineering courses every engineer takes.
Engineering Statics
Analysis of rigid bodies in static equilibrium — forces, moments, trusses, frames, friction, centroids, and distributed loads. The first core engineering course and gateway to Dynamics, Mechanics of Materials, and Fluid Mechanics.
Engineering Dynamics
Kinematics and kinetics of particles and rigid bodies — motion analysis, force-acceleration, work-energy, impulse-momentum, and vibrations. Extensively builds on Physics Mechanics and Statics.
Fluid Mechanics
Fluid statics, kinematics, and dynamics — pressure, buoyancy, pipe flow, boundary layers, and dimensional analysis. A cross-cutting course connecting Thermodynamics, Dynamics, and Heat Transfer.
Thermodynamics
Thermodynamic properties, first and second laws, power and refrigeration cycles, and chemical thermodynamics. The physical foundation for all energy conversion systems — power plants, engines, refrigerators, and chemical processes.
Mechanics of Materials
Internal forces, stresses, and deformations in structural members under load — stress/strain, axial loading, torsion, bending, combined loading, pressure vessels, beam deflection, and column buckling.
Mathematics
The mathematical tools that power engineering analysis.
Linear Algebra
Matrix algebra, vector spaces, linear transformations, eigenvalues, and orthogonality. Every concept is introduced geometrically before algebraically — understand what matrices do to space.
Math Foundations
Pre-calculus mathematics required before entering calculus-based engineering courses — algebra, functions, geometry, trigonometry, exponentials, logarithms, and complex numbers.
Calculus I
Limits, derivatives, and integrals of single-variable functions. Every concept introduced with geometric intuition before algebraic formalism — understand what a derivative really means before computing one.
Calculus II
Advanced integration techniques, sequences and series, parametric and polar curves. Builds the full integration toolkit and introduces the paradigm of infinite processes — can an infinite sum converge to a finite number?
Calculus III
Multivariable and vector calculus — partial derivatives, multiple integrals, vector fields, line and surface integrals, and the fundamental theorems (Green's, Stokes', Divergence) that generalize the FTC to higher dimensions.
Probability & Statistics
Probability theory, statistical inference, and data analysis for engineers — descriptive statistics, discrete and continuous distributions, confidence intervals, hypothesis testing, ANOVA, regression, quality control, and reliability. Covers all 8 FE disciplines, AP Statistics, and full university curriculum.
Sciences
Physics and chemistry — the physical foundation for all engineering.
Physics — Mechanics
Calculus-based mechanics covering kinematics, Newton's laws, energy, momentum, rotation, oscillations, and gravitation. The foundational physics course that shares concepts with Statics, Dynamics, and Fluid Mechanics.
General Chemistry
Atomic structure, bonding, stoichiometry, thermochemistry, kinetics, equilibrium, and electrochemistry. Chemistry provides conceptual grounding for Thermodynamics, Materials Science, and Fluid Mechanics.
Physics — Electricity & Magnetism
Calculus-based electricity and magnetism — electric fields, potential, capacitance, current, magnetic fields, induction, Maxwell's equations, and optics. The physical foundation for Electrical Circuits.
Organic Chemistry
The chemistry of carbon compounds — structure and bonding, stereochemistry, reaction mechanisms, functional group transformations, spectroscopy, and retrosynthesis. From hybridization to multi-step synthesis.
Applied Engineering
Specialized topics connecting theory to practice.
Electrical Circuits
DC circuits, AC steady-state, transient response, frequency response, and op-amps. Operationalizes the physical laws from Physics E&M into systematic circuit analysis techniques.
Engineering Economics
Economic decision-making for engineers — time value of money, equivalence analysis, rate of return, benefit-cost analysis, depreciation, and inflation. One of the most heavily tested FE exam sections.
Aerodynamics
Fundamentals of flight and aerodynamic analysis — airfoil theory, lift and drag prediction, boundary layers, finite wing theory, high-speed aerodynamics, and aircraft performance. From Cessna to supersonic.
Astrodynamics
Orbital mechanics and space mission design — the two-body problem, Kepler's laws, orbital maneuvers, interplanetary trajectories, re-entry mechanics, and spacecraft attitude control. From ISS to Mars.
Aerospace Systems
Flight dynamics, propulsion, and aerospace structures — aircraft stability and control, rocket and jet engine analysis, structural design with composites, and advanced propulsion concepts. From autopilots to scramjets.
