Hi! I'm Karissa, and I have been a tutor for 4 years with a focus on high school math and science. I am currently studying Environmental Biology at Cal Poly Pomona because I want to find a career that involves conservation efforts. I love to tutor because it allows me to share my passion for learning with others and I hope to inspire others to inquire about the world around them. The world is filled with wonders, so let’s learn about them together!
