How to best prepare for college-level engineering?

I'm a junior and thinking about engineering for college. What are some ways I can prepare now to be ready for the college-level engineering coursework? Any classes or activities that helped you?

Engineering is a demanding discipline that requires a depth of knowledge and understanding in mathematics and science. Here are a few suggestions to help you prepare for college-level engineering:

1. Math and Science Courses: If possible, take advanced courses in calculus, physics, and chemistry in high school. These are foundational subjects for the engineering coursework you'd be undertaking in college. Even computer science classes would be beneficial if you are leaning towards fields like Computer Engineering or IT related Engineering disciplines.

2. Extracurricular Activities: Participate in STEM-focused extracurricular activities or clubs in your school. Joining a Robotics team, Science Olympiad, or a similar club can provide you with practical experience in problem-solving and teamwork—both of which are critical in engineering.

3. Summer Programs: Look into summer programs or courses that offer insight into engineering fields. These programs can offer a deeper understanding of what it's like to be an engineer, and could include hands-on projects, seminars, and lab experiences.

4. Online Learning: Platforms such as Coursera, Khan Academy, and others offer free courses in calculus, physics, chemistry, and even introductory engineering. These can supplement what you're learning in school and might give you a flavor of college-level coursework.

5. Project-based Learning: Consider personal projects that involve problem-solving and critical thinking. This could involve working on a DIY electronics project, coding a mini application, or even designing a solution for a problem in your local community.

6. Learning from Professionals: Consider job shadowing or internships at local engineering firms or companies if possible. This real-world exposure can give you a better understanding of what it's like to work as a professional engineer.

Remember, it's not just about piling on more work. It's also about exploring the fields, getting hands-on practical experience, and figuring out which aspects of engineering most excite you. So, approach your preparation with curiosity and a willingness to learn rather than just box-checking. Doing so will bring rewards not only in terms of college preparation but also in shaping your perspective of the field.
