Science subjects can be difficult, but very interesting and useful once they are understood. I am a fourth year undergraduate student studying Chemistry and Chemical engineering, and I offer help with high school courses, lower year university ones, or simply tutoring for people interested in the subject. Since I have followed an engineering-based degree the first two years, I have strong bases in most of the scientific subjects, such as calculus, algebra, chemistry and biology, and am glad to help anyone that might need it to understand them better.
