This is a great opportunity to get involved at McGill, while helping your fellow students through their coursework. Not only will you feel more integrated within the SUS community, you will also feel very rewarded after a semester of tutoring.
If you plan to take the MCAT, the material is almost identical to the first and second year science courses, so this is a great way to prepare and keep that info fresh in your mind!
You get to meet new people, which is always a benefit to volunteering!
