If you are a freshman now, I suggest that you can choose a young teacher with good academic performance in your college as your undergraduate tutor. If you have any ideas about scientific and technological innovation, you can talk to your tutor, let him be your tutor, and guide you to apply for some undergraduate scientific and technological innovation projects, including the national college students' innovation and entrepreneurship training plan and some scientific and technological innovation projects in your school. Through these innovative projects, if you do some scientific and technological innovations, inventions and social practice surveys, you can participate in some national competitions in your sophomore and junior years, including the Challenge Cup and the Energy Conservation and Emission Reduction Competition. , so as to enrich their undergraduate competition experience, cultivate their scientific and technological innovation ability, and pave the way for postgraduate study. I hope my answer can help you, thank you!
