Benefitted from some of the Crash Courses (chemistry and math were both good) but found their physics was less good than Gradesavers or other tutoring companies
Quality of instruction and course materials varies.
Some crash courses are superficial and regurgitate exactly what is in the course slides or book. For $120 and 12 hours of your life, you are better off just taking that time and reading the slides or book and then hiring a private tutor for weak areas. Very little value for money and time in terms of learning more than you could on your own with the materials you already have. Not enough problem solving to help prepare for an exam.
On the other hand, some of their more experienced tutors are truly excellent teachers and know how to teach a class of students who are at varying levels. In particular, Amy for chem is probably the best in the city and is even recommended by professors at Concordia and McGill.
Chet from Gradesavers has a much better reputation for physics.
In summary, the company has some good tutors and some not so great ones, depending on your expectations. read more
