I think you've confused a few implications. Firstly, don't proceed by assuming w_2n is divisible by 11, but apply the palindromic nature of the coefficients to w_2n first. If u_2n is palindromic, a_k = a_(2n-1-k) for all k, then w_2n = 0, and then you can make the argument u_2n is divisible by 11.
Some good answers were provided in this thread. Another approach is to brute force the answer by algebra;
\frac{n!}{6!(n-6)!}=\frac{n!}{4!(n-4)!}
\frac{(n-4)!}{(n-6)!}=\frac{6!}{4!}
(n-4)(n-5)=30
... and solving this quadratic gives the solutions n=10 and n=-1, the latter is disregarded.
CLAW1001: Foundations of Business Law
Ease: 5/10
Lecturer: 7/10 (Note that the lectures are online videos)
Interest: 9/10
Overall: 7/10
The content was thoroughly interesting and the application of it is also quite practical (unlike HSC legal studies where you learn the law and discuss the...
That's every weekend, public holiday and weekday outside of the semester hahaha.
Anyways my advice is to make sure you get all your free shit from the stalls and also join any peer mentoring programs your faculty is doing (where you will also get more free shit).
I recommend using the dot points from the 'learn about' section word-for-word as subheadings for your notes. The 'learn to' section makes good questions as you said (particularly as essay questions in economics), and it's also a good way to check your revision by skimming over them and asking...
You can see how long each class will be at usyd by looking at the timetable preview https://timetable.sydney.edu.au/even/timetable/#subjects
For most classes, each subject each week involves a 2-hour lecture, and 1-2 hour tutorial. The exception is science, engineering and maybe medicine...
The first time I tried it I submitted a photo on 25/01 and it got rejected on 27/01. Then I tried it again in late february and it accepted in 1 day. Keep in mind that after it accepts, you have to wait another 2+ weeks later to collect it. But since you're doing it so early, you should be fine...
Yep timetable preferences open and close on the days you listed in your comment above. Even if you somehow forget to do preferencing, they will still allocate you to class.
But at this point you can see what class times will be available for Sem 1 2024...
There is exams, which would usually be a final exam and sometimes a mid-sem too. Find the subjects you need to do for the degree you want and search "[Unit code] unit outline" and you should be able to see the assessment structure.
I lost access to look at my school gmail inbox around April. But all the other google services related to the account (docs, sheets, slides, even classroom) are all still there... a full 12 months after my HSC.
If you use a paper logbook (which I recommend - because it's easier to forge the hours lol) then take a photo of every page as it is completed so that you can just recopy all the info if you lose it.
Great advice, but please do not use the UNSW library and consider finding another location to study in. Remember that the library is provided for the benefit of Year 12 students only.
