Hi Pavan,

What High School Courses Are Needed to Study Chemistry in College?

Here's a list of good courses to take:

Algebra
Understand ratios, direct proportions, and inverse proportion.
Solve linear and simple nonlinear equations.
Set up word problems.
Identify dependent and independent variables.
Understand the slope and intercept of a line.
Be able to graph data points.
Understand exponentials and scientific notation.

Geometry
You'll need this to understand bonding, molecular models, and crystal structures.

Trigonometry
You'll need trig for much the same reason as you need geometry. Plus, trig is essential for completing physics.

Pre-Calculus
You have a lot of calculus in your future. Hope you enjoy it!

Physics
Physics and chemistry are inseparable. If you major in chemistry, you'll still take college physics. If you major in physics, you'll take chemistry.

Chemistry
In addition to making college chemistry a bit easier, high school chemistry gives you a taste of what the science is all about. Be sure to master these concepts:
Be able to define atoms, molecules, elements, and compounds.
Be familiar with the periodic table and know the symbols of common elements.
Understand how to read a chemical formula (e.g., H2O).
Know what a 'mole' us.

In addition to this list, it's a good idea to be proficient with a computer and keyboard. Statistics and biology are also useful courses, although your schedule probably won't allow you to take everything you want!
