hey the sessions are an hour and half long and cover the key material on the exams. They are led by experienced tutors who have taken these courses and can help with tips and tricks for the exams!
As well, the review package consists of notes covering the span of the course and practice questions. The packages are generally between 20-30 pages in length!
As well, all the money raised from the session, (which is only 20 dollars per session) goes to help build sustainable projects in third world countries!
feel free to ask any more questions!
