Key Takeaways
- In chemistry, connect atomic structure to periodic trends, bonding, reactions, and solution behavior.
- In physics, start with relationships among force, motion, energy, waves, electricity, and magnetism.
- Conservation ideas are high yield: mass, charge, and energy are often the anchor concepts.
- Many wrong answers mix up closely related ideas such as mass vs weight, speed vs acceleration, or current vs voltage.

What to Prioritize in Physical Science
This domain mixes chemistry and physics, so your review should stay organized around the major systems:
Chemistry Priorities
- atomic structure and periodic behavior
- ionic vs covalent bonding
- physical vs chemical change
- balancing simple reactions and conservation of mass
- solutions, concentration, pH, acids, and bases
Physics Priorities
- speed, velocity, acceleration, and Newton's laws
- work, energy, and conservation of energy
- heat transfer and phase change
- wave properties, sound, and light
- circuits, current, voltage, resistance, and magnetism
Fast Solving Habit
When a physics or chemistry item looks dense, ask:
- What is conserved or changing?
- What variables are directly related?
- What concept is the distractor trying to confuse?
That habit prevents many avoidable misses on otherwise familiar content.
