Physics teacher | Verified Expert
With a Physics degree from the University of West Florida, I'm passionate about unraveling the mysteries of the universe. As a dedicated tutor, I bring clarity to complex concepts, making physics accessible to all. My goal is to ignite curiosity and foster understanding in every student I work with. Let's embark on a journey of discovery together!
