A fantastic subject! The content is interesting but also challenging when you need to get acquainted with lots of new concepts. The lecturer Aihua Xia explains things comprehensively and is very friendly. The assignments are doable with only a small portion of tricky questions. The exam was quite hard because you need to deal with many questions including challenging ones in a constrained time. So it is best to practice a lot before the exam to make sure you can do all the easy questions and can manage your time well. Overall, highly recommended subject for math and computer science majors!

A very difficult subject, starts of easy with basic probability review but gets real hard real quick. Look at taking Probability for Statistics (much easier and still a prereq for stats - also can be a prereq for probability for inference with a mark of 60). Definitely doable if you stay on top of lecture content and constantly revise, just be prepared for a lot of work

A difficult subject. Probability for statistics is much easier.

Fantastic subject! Xi is an incredible lecturer, Tim Banova is a wonderful tutor and the subject is really quite amazing!

Very content heavy subject but Xi Geng was an amazing lecturer. Explained concepts really well and was so responsive (albeit COVID/online delivery) to any questions you might have. Would highly recommend doing it when he’s the lecturer! Assignments were doable although it was a bit heavy for a mere 5% but they kept me on my toes. Not a subject you can afford to slack because of how fast paced it is and it’s easy to get lost if you don’t keep up. Might also be a little challenging if you didn’t do Real Analysis because understanding the derivation of Taylor Polynomials and Power Series is essential for some derivation in this subject. Overall a doable subject if you keep up with lectures, tutes and past years were of great help to me.

It is a vey interesting subject. However there are a lot of concepts to grasp in a short period of time. Make sure to be consistent!

Very Hard Subject when taught in the first semester!!! Managed to score better in semester 2 which the exam was fairly understandable!!! if you have to deal with a lot of basic, cdfs, pdfs and continuous and discrete functions in one A4 sheet of paper you only have to know some of them!!! Very difficult the first time but second it was a different lecturer teaching this subject. Take caution before taking this subject!!!!!

I find this subject really hard, i spent time trying to understand the concept, but it was still hard. Even listening to the lecture does not really help. People said probability for statistics is easier.

I did this subject waaay out of order, after a heap of other second year maths and some third year as well, and I found it to be reasonably difficult. Doing this after nothing but Calc 2 + Lin Alg would have killed me. This is a really, really hard subject for an introductory second year maths subject. If you can get past all that, however, it's a really beautiful one IMO. The tools you learn have clear practical implications, and there are a lot of nice "aha!" moments. A good old unimelb MAST 80% exam so be prepared for this one.

Definitely a hard subject, I scraped through though I enjoyed the experience thoroughly. Aihua is an incredibly humble man and a great lecturer who always made the theatre laugh though he is also an unforgiving exam writer. Subject is dense in content, though it is less heavy in the first and last topics. Common criticism is there are not enough examples on the slides and the lecturers don't cover as many as you would expect coming from Calc2 and LA. The subject aims to build an intuition, rather than become another that you learn to apply formulas with. However this is a bit annoying when they have stuff like Taylor series and proofing methods that are not properly covered in the pre-reqs, so it can be a bit daunting if you haven't done vector calc/real analysis. And as always, exam scaling is your best friend.
