If you find that you need extra help in a class, check with your professor or teaching assistant first to see if they can offer you some additional help. If they have office hours, go to them. While private tutors are helpful, your instructors understand what you need to know best and how you are doing in their class. If they are not able to offer you additional help, they could possibly recommend reliable tutors. Many departments have their own organized system for free tutoring. You will also see many ads for tutors around campus and in the Lantern. Check with a few tutors to compare prices and services.
