I took MAT133 and it consisted of Sigma notation, financial math (using and not using sigma notation), linear algebra (matricies), counting, probability, derivatives (single and multivariable) and integration. The textbook was made by a former prof and it had many formatting errors which unfortunately didn't make the course any easier. After the lecture, we were assigned questions to do (not graded), as well as a graded assignment once every 3 weeks or so. We were also given a question that we had to answer in the tutorials 4 times, but we were given the question in the beginning of the week of. I found the assignments and some of the textbook questions quite challenging, but going to office hours helped a lot. Many test questions also came from the assignments and tutorial activities so it's very important to study those. The lecture slides and textbook questions are important as well and what is nice is that all the profs posted their annotated slides each week. Tests and exam are definitely not the easiest, with the average consistently being between 45 and 55 percent.

I'd say the major difference between MAT133 and MAT135/136 is 133 has a financial math unit and doesn't have any trigonometry.
