Statistical class and Students' Anxiety

The class has not yet started; yet many students who enrolled in the statistical methods class are getting very nervous. They are looking for supplemental materials - other than the textbook. Some of them even asked me what kinds of calculator should be used for statisitcs course. Oh boy! I can tell fromt heir faces. Everyone is very nervous. I am the librarian not the course councelor. I hope I can give them extra support and relieve some of their stress.
