I have been tutoring for over 3 years and have experience with a variety of students, from those who are struggling to keep up with their class to those who are looking to get ahead. I specialize in English and writing, but I am also proficient in math and science. I am patient and adaptable, and I work with each student to find the best methods for them to learn and retain the material.
