You may come across big numbers which you need to divide if you keep collecting terms at each stage, but it will be manageable if you break it down into its components. They wouldn't ask this questions directly, it would just be part of algebraic manipulation.
2408/36= 1204/18 = 602/9   which doesn't simplify further as 602 is not divisible by 3.     You would need to leave your answer in the form 602/9 to get full marks.

I'm going to assume you meant 15*7? in which case, you could do 15+15=30, +15= 45   +15= 60 etc until you got to 105,      or 7*5=35  35*3= 105    or  7*5= 35, 7*1=7   7+3= 10    105   

The examiners aren't testing you on these skills; this is not the focus of the exam, but you may need to do simple sums in order to get to the answer.
I repeat, they WILL NOT ask you a question saying "Evaluate 54*73"       but you may need to do multiple digit multiplication and division as part of your working out. They won't give you any question where you are required to do something overly difficult, this is just assumed knowledge from previous years
by 15c7 i meant the probability one, with factorial, like do you reckon they could ask that in exam 1, as it takes a really long time to work out by hand?

It is VERY VERY unlikely that they would

that's a relief to hear, as frustratingly i had that question 15c7 in my unit 2 methods sac, which was tech-free (no notes or calculator)

never seen a question on exam 1 where you are forced to use combinatorics or factorials since there is usually easier (or harder, depends on preference) ways to do the questio.

I'm going to chime in here and firstly say that there is quite a large amount of difference between unit 1&2 methods compared to 3&4, especially since the introduction of the new 1&2 course. A 32 in Methods is quite an average score, an average student, performing at an average level can expect to get a 30. Slightly above that at 32 is the same person on a different day with a different exam.

I don't mind suggesting you to rote learn theory if you are not confident in your ability to understand. I don't recommend it, but if you are not aiming for the highest score possible it is certainly a viable option.

Probability is also drastically different in 3&4, with more focus on the various distribution and their theory as opposed to calculations. You are expected to know your combinations and permutation formulae but the change you see a difficult one is unlikely. And even if you did, it is just a bit of tedious multiplying.

A 32 is achievable if anyone takes some time to forcibly remember theory, you won't score well, and you will benefit very little from the subject but you will get the score to get that ATAR you need for your course where you'll never see methods again.

Thanks for that!
Also, do you know how much harder methods 3/4 is compared to methods 1/2? And the possible exam scores needed for a 32 raw?

depends what sort of sacs you were set in 1/2. Of course it will be "harder" however methods is one of a few subjects where untis 1 & 2 content is directly applicable for 3/4 since most of 3/4 is just an extension on 1/2.

For a 32
i'll consider 2015 since it was a standard exam
24/40
and
45/80 should comfortably get 32 i reckon.

Does it matter which exam you do better/worse on?
Like, would 30/40 and 50/80 yield the same study score as 40/40 and 40/80?

Well it technically it does
You wouldn't think so considering
Exam 1 = 22% 40marks
Exam 2 = 44% 80marks

However when calculating study scores they take your standerdised score for each exam hence exam 2 is worth more per mark especially at the high end where the frequency of scores at the top end is much less for exam 2 than exam 1.

I would think/worry about any of this for scores 30-35 :P

I think I failed my circular functions and probability sac (<40%). Is it still worth aiming for a 35+ raw study score for year 12 next year?
Any way to improve on probability?

Absolutely no need to stress about study scores for next year :)

I personally found 1/2 Methods pretty different to 3/4 Methods, so your performance in 1/2 isn't necessarily an indicator of your performance in 3/4. Also, you've got so long to work on improving your skills! No need to resign yourself to a particular study score at this point in time (I'd argue there's never a need to resign yourself to a study score in general!). The only thing that can you from scoring what you want to score is yourself and how much you put in.

Probably worth having a chat to your teacher on how to specifically improve - they'll likely have some great insights that are super specific to you! Apart from that, maybe work on recognising where you go wrong in questions, work on recognising what a question actually wants you to do, etc. I'm sure one of the Methods gurus on the forum will be able to chime in with some more helpful and specific tips at some stage, but until then, maybe have a look through the guides and useful threads that are on the forum, and maybe see if there's any articles that are relevant to you! :)

Yes,  there certainly is hope.  People have made much more dramatic improvements between year 11 and 12 in the past

Are the sac scores you need for a particular study score before or after moderation?
