I have been a tutor for over 3 years and have had the opportunity to work with students of all ages and backgrounds. I have a strong belief that all students have the ability to learn and succeed if given the right tools and support. I am patient and adaptable, and I take the time to get to know each student's individual learning style in order to best support their needs. I am confident in my ability to help students improve their grades and reach their academic goals.
