Many undergraduates contemplate graduate study, but find it intimidating or difficult to start the process of applying. Professors should know you well enough to write letters of recommendation. Start out by taking more than one class from the same professor. Look into becoming a research assistant, helping professors with service activities or assisting them with their teaching.
Many departments have noncredit seminars that undergraduate students can attend.
By attending these seminars, undergrads can meet professors and learn about the activities of graduate students. Distinguish yourself from other undergraduates applying to graduate school. One way of making your application stand out is by having research experience. Some schools require a statement of research and career interests. Identify the current, not past, research interests of faculty at the different graduate schools you are applying to, and link your research interests to those of the faculty.
