The Toronto Life Sciences Group helped me achieve a great mark in MAT 135 because of the great techniques that James taught. Ultimately, MAT 135 is a course of recognizing patterns, and utilizing the corresponding technique. What I found helpful was that James went through many different types of practice problems as well as previous exam/test questions step-by-step so that you can see the method that must be taken in order to solve the problem. Over time, his way of teaching enabled me to look at a problem, and then realize the method to be used quickly, which helps when you have 15+ pages of exam to get through! You should choose TLS because you'll learn a great deal, get lots of practice, and achieve great marks!
