Free Online Resource For Math, History And More
You would not bring a hippo to campus with you, but the website, Hippocampus, brings home information on subjects taught in high school and college that might help you earn an A in class.
The entire site is free, and offers electronic material in math, such as algebra and calculus, that goes through course material concept by concept. Other areas, such as history, feature short videos, key documents, and background information to help you understand your classes better. It even features several courses entirely in Spanish, for students and parents who prefer to read it in that language.
