85%+ cold

You're likely ready for the official Physics Credit by Examination. Register with your counselor and take 1–2 full timed mocks to lock it in.

70–85%

Solid foundation, real prep needed. 4–6 weeks of timed mocks ($19.99 / 6 mo) with AI explanations on every wrong answer.

Under 70%

Concept-level gaps. Start with the Concept Lessons below, then return to practice once the underlying topic clicks.

Passing-score thresholds vary by district (Texas state code: 80% for §28.023 acceleration, 70% for §74.24 prior-instruction credit). Confirm your specific district's threshold with your school counselor in writing.

Visual lessons that build Physics from first principles — diagrams, worked examples, embedded practice.

Concept Lesson · 10 min· TEKS 1

Physics 1A: Scientific Processes & Measurement

Lab safety in the physics classroom, the scientific method as a discipline, measurement precision and accuracy, SI units, and how graphs let you read motion. The foundation the CBE expects you already have.

Concept Lesson · 12 min· TEKS 2

Physics 1A: Motion in One Dimension (Kinematics)

Position, displacement, speed, velocity, and acceleration — the language physicists use to describe motion. The four kinematic equations that solve almost every 1D problem on the Physics Semester A CBE. And how motion graphs let you skip algebra entirely.

Concept Lesson · 14 min· TEKS 3

Physics 1A: Newton’s Laws & Force Applications

Newton’s three laws — the framework physicists use to explain every motion problem in Physics Semester A. Weight vs mass, free-body diagrams that catch algebra errors before you make them, and the subtleties of action-reaction pairs that most students get wrong.

Concept Lesson · 13 min· TEKS 4

Physics 1A: Gravitation & Fundamental Forces

Newton’s law of universal gravitation, the inverse-square dependence that changes the answer by a factor of 4 when you double the distance, weight vs mass on different worlds, and where gravity sits among the four fundamental forces.

Concept Lesson · 15 min· TEKS 5

Physics 1A: Energy, Work, Power & Momentum

The three currencies of mechanics — energy, momentum, and power — and the conservation laws that make almost every problem solvable without tracking each force. Work-energy theorem, kinetic vs potential energy transformations, impulse, and the difference between elastic and inelastic collisions.

Concept Lesson · 14 min· TEKS 6

Physics 1A: Thermodynamics

Temperature vs heat — one of the most-tested distinctions in Physics 1A. Specific heat, three modes of thermal energy transfer, engine efficiency, thermal expansion, and the laws of thermodynamics that constrain what any physical process can and cannot do.
