## What do you learn in Computational Chemistry

Computational Chemistry blends chemistry, physics, and computer science to solve chemical problems using mathematical models and simulations. You'll learn about molecular modeling, quantum mechanics, and how to use software to predict molecular properties. The course covers methods like density functional theory, molecular dynamics, and Monte Carlo simulations to study chemical reactions and molecular behavior.

## Is Computational Chemistry hard?

Computational Chemistry can be challenging, especially if you're not comfortable with math or programming. It's not just about memorizing chemical facts, but applying complex algorithms and understanding abstract concepts. That said, many students find it rewarding once they get the hang of it. The hardest part is usually wrapping your head around the quantum mechanics stuff at first.
