any tips on how to overcome the difficulties of this course?

Depends. What kind of difficulties are you having? Overall, I'm finding it to be pretty straight forward so far. The textbook is pretty good.

are you going to lectures and tutorials regularly? I took this course last year and it was one of my highest marks.

Depending on the difficulties, always ask your TA or the prof for questions regarding the course contents you have problems. They are more than happy to help you. Attend lectures and tutorials regularly for sure.

Doing one of the assignments right now. EASY.

If you have the texbook and study guide, they are very helpful for explaining the different concepts. Dr. Moro also posts her podcasts on avenue so if you are having trouble understanding a certain concept, you can always re-watch her explanation in lecture. If that fails, there are plenty of opportunities to meet with the TAs and Dr. Moro so they can clarify the parts of the class that you are struggling with. Don't be afraid to go talk to your TAs and professor. If you put a solid effort into the class and aren't afraid to ask for help when you need it you will be fine.
