Interested in Becoming a COSINE Tutor?

Most tutors join the program as a substitute tutor, then become a routine tutor as spots become available. Applications are reviewed at the end of each semester to fill open spots for the upcoming semester. Therefore if you apply early in the semester, your application may not be reviewed until the end of the semester. More information is forthcoming about applying.
