A high school senior with a strong background in chemistry is considering a career in physics and seeks advice on college classes and decision-making. It is noted that students majoring in chemistry, physics, or engineering typically need to complete general chemistry and calculus-based physics sequences, emphasizing the importance of a solid math foundation. The first two years of coursework are often similar across these fields, allowing for exploration before declaring a major. The discussion highlights the significance of lab work in both disciplines, suggesting that hands-on experience may help in determining which field aligns better with personal interests. Additionally, staying informed about current research in both physics and chemistry can aid in making an informed decision.
