I have been teaching high school chemistry, physics and math for 22 years. Before becoming a teacher, I was an aerospace engineer for 12 years – yes, I am a rocket scientist! You, however, do not have to be a rocket scientist to succeed in math and science. I have tutored many students and helped them improve their math and science skills and grades over the years. When tutoring a new student, or an old student in a new subject, I first assess what you already understand. From there, you and I.
