As I've said on my other posts, I will be studying at the University of Melbourne next year as a mature aged student. I was told that I need to at least know the content in VCE Maths Methods (CAS) units 3/4. The problem is that the most advanced mathematics I can do at the moment is addition, subtraction, fractions and decimals - and even that takes a while!
just clarifying - you've got to from your current level of maths, to a level where you can complete VCE methods 3/4, by the time uni starts?
I think it would be very hard and this is gonna take
alot of work in this amount of time. I really dont think it is possible though to get to a completed methods 3/4 level in a few months when you start off not knowing how the cartesian plane works.
i spent my summer holidays going into year 12 spending hours and days trying to learn stuff that i didnt know from 1/2 methods and year 10, and i was still miles behind when 3/4 started, let alone being at a level where i could complete 3/4. Granted i had other subjects to worry about, but from looking at your other posts it looks like you do too. As sir.jonse said above me
How long did it take to master these basics? I would say about a month or two, It wasnt easy though, it was really hard.
and that isnt even touching 3/4 level which would take MUCH longer
It would
definitely be possible however to get up to pre-3/4 methods, and learn things well, and then pick up MAST10012 introduction to mathematics in first semester
https://handbook.unimelb.edu.au/view/2014/MAST10012, and make sure your other 3 subjects that semester involve as little methods sort of math as possible
but if you were to self teach - here is how i would approach it
grab a year 10 maths book and just go through the khan academy maths, and after each lesson, do some practice questions from the relevant chapter of the year 10 maths book(such as mathsquest year 10). once youve mastered all the stuff in that textbook, and know it all well, grab a methods 1/2 textbook (forget further LOL it wont help) and do the same thing, learning as you go through khan academy and doing practice questions. if khan academy begins to exceed methods 1/2 stuff without covering all of the topics then learn those uncovered topics before you move onto the 3/4 book. if khan academy cant help then you can post on atarnotes in one of the methods question threads.
once youve finished your khan academy/methods 1/2 book, grab a methods 3/4 book, and work through the book, with khan academy and atarnotes and vtextbook supplementing you and teaching you, until you complete it.
im thinking the first introduction to quadratic equations, and the whole of methods 3/4 will take up most of your time.
this is just my 2 cents and everyone will have different opinions on how to approach this and the possibility of it all

so keep that in mind
i just want to say though that i am glad to see that you are going back to uni as a mature age student and havent given up on education, it will be hard but definitely not impossible and im sure you will feel very fulfilled and be greatly rewarded once you get through uni

best of luck in whatever you do !! and if you ever have questions about anything im sure there will be someone on atarnotes to help you out
