There is always an ultimate user "root" in Linux, who has the right to do everything. Since the password is not yet set for "root", it is impossible to login in as root. However, a "sudoer" user, which is "student" in our case, may upgrade itself to "root" via the command sudo: execute$ sudo sufollowed by entering the password of "csci3150".
