Flash-Pass TL;DR
  • Science track covers physics (40%), chemistry (35%), and biology (25%)—prioritize based on weighting.
  • Focus on conceptual understanding and formula application rather than memorization.
  • Practice with data interpretation questions, which appear frequently in all three subjects.

What Does the Science Track Cover?

The CSCA Science track tests your knowledge of physics, chemistry, and biology at the high school level. Questions are distributed as follows:

40%
Physics
35%
Chemistry
25%
Biology

Allocate your study time proportionally, spending more time on physics and chemistry.

Physics: Key Topics and Formulas

What physics concepts appear most frequently?

Physics questions focus on mechanics, with some electricity and waves. Master these formulas:

Essential Physics Formulas
ConceptFormulaCommon Application
Velocityv = d/tMotion problems
Accelerationa = Δv/ΔtChanging speed
ForceF = maNewton's Second Law
Kinetic EnergyKE = ½mv²Energy problems
Potential EnergyPE = mghGravitational energy
Ohm's LawV = IRCircuit problems
PowerP = VIElectrical power
🔬Scientist's Note

Mechanics (motion, forces, energy) accounts for approximately 60% of physics questions. Master these concepts first before moving to electricity and waves.

Chemistry: Core Concepts to Master

Chemistry questions test conceptual understanding and basic calculations. Focus on:

Biology: High-Yield Topics

Biology is the smallest section but still important. Prioritize these areas:

Data Interpretation Skills

A significant portion of science questions involve interpreting data from graphs, tables, and experiments. Practice:

🎯

It depends on the solution

Frequently Asked Questions

You should know common elements (first 20, plus common metals) and understand periodic trends. You don't need to memorize the entire table.
No, calculators are not allowed. Practice doing calculations by hand, especially stoichiometry problems.
High school level is sufficient. Focus on major concepts rather than minute details.
No, allocate time based on question distribution: 40% physics, 35% chemistry, 25% biology.
