For the most part, I quite enjoyed it! It was a good continuation to MATH1131/1141, and most of the content itself was quite interesting. Algebra was basically a bit more on vectors (how we define vector spaces, subspaces, etc), before diving into the ideas of transformations and probability/statistics. It wasn't hard and required minimal studying to get by, and I recommend doing most of the problem sets (although quite tiresome and repetitive) if you're really aiming for a Distinction or High Distinction. Otherwise, minimal studying is required to pass.
For Calculus, we began discussing the idea of polynomials as a way to approximate a non-polynomial function. This was captured in a topic called "Taylor Series". Most of the Calculus-related aspects could technically be taught in Extension 1 or 2, as they aren't hard concepts to grasp. As mentioned above, minimal studying is required to pass so if you're looking for a pass/credit, you don't need to do much. But this should be a subject where you're getting Distinctions/High Distinctions.
From week 2 to week 13 (not sure what it is now due to trimesters; week 10 I think?), there is a Calculus/Algebra online tutorial that you must complete and the best 8/12 of them counted. It should be an easy 12% to achieve since you have unlimited amount of attempts so uh you should technically be getting close to 100%.
