What is the difference between Math Drop-in and Math SI/Tutor Sessions?

Math Drop-in services are provided in-person (Bolton 180) and online drop-in during specific times and hours. Tutors can work with you one on one on specific concepts or themes within your math course. Drop-in tutors can support students enrolled in the following courses: Math 92/102, 94, 98/108, 103, 105, 115, 208, 211, 213, 221, 231, 232, 233, 234. Math Stats 215 is only available on certain days throughout the week which can be found on the Drop-In Tutoring page.   

Math SI sessions are held at the same time every week. Students can drop in during scheduled SI sessions and are not required to sign up in advance. SI sessions are typically larger than tutoring sessions. SI Leaders attend regular lectures for the course and prepare agendas and activities for their sessions. SI Leader will also hold exam reviews. Math tutoring sessions are small-group sessions (smaller than SI). Tutors have experience taking the course before, but they do not currently attend the lectures.
