Hi, thanks for your question! I’m really glad you have a passion for science— that is the first step in becoming a great scientist. Don’t let your grades in physics affect your pursuit of science and quenching your curiosity for comprehending scientific knowledge! I myself did not do so well in biology fields, but I chose instead to focus on physics and chemistry. I eventually found my passion in electronics and materials science & engineering. Science, after all, is a huge field, with many different options to choose! You can still pursue many areas without needing physics in your repertoire. For instance, as a chemist, a biologist, or a medical doctor, you need to be adept at chemistry and biology, fields which you already find yourself good at. You may also find yourself combining other fields like mathematics or computer science in the future, and an understanding of logic will really help there. Look for unique topics in the fields you are strong in, and always be open about new possibilities. Either way, stay strong in school and you will eventually find something in science that hooks your passion!
