Physics teacher | Tutor for 6 years

I hold a degree in Physics from Johnson and Wales University. With a passion for unraveling the mysteries of the universe, I bring a deep understanding of scientific principles to my teaching. Whether it's explaining complex concepts or guiding students through problem-solving, I'm dedicated to fostering a love for learning and helping students achieve their academic goals. Let's embark on a journey of discovery together!

## Questions
