I think being a student is the best time in our lives. In spite of lot of studies, each student always has the time to find new friends and hang out with them, but those same students have lot of questions when the semester is about to end and the times for exams come.
Course Hero is a place where you can get answers to your questions. It is an open coursework website for college students. When you join the website you can get textbook solutions and study materials.
Hope you can find lot of interesting things in this site :)
