I find it quite straightforward, but it is easy to slip up in linear programming (especially when writing the constraints). Any suggestions to address this issue?

Well, I don't know how effective this will be for you, but whenever the question provided information in worded form and asked us to create a constraint, I would check my answer by substituting random values to make sure that the constraint was right.
eg. 2012 Exam 1: Graphs and Relations q 8
at least 5 loves of white bread will be made for ever loaf of brown bread that is made
w= white bread made per day
b= brown bread made per day
I'd first write up my constrain: w ≥ 5b
I'd then check this by subbing in random values for b. So, if I made 1 brown bread, I'd made 5 white bread. If this matches the constraint they provided originally in words, you'd know you have the right answer.
Hope that makes sense. :P

I have my first SAC this Wednesday (my school divides the CORE Sac into Univariate and Bivariate data). Does anyone have any tips for the univariate section?

Yes, heaps of kids get these wrong! If you can get your head around this, you're looking really good. :)

Knowing you, you probably just need to slow down and read each question carefully.

LOL Knowing me? hehe what do you mean, do I jump the gun?! :p

No, you've probably covered every single little thing in univariate data really thoroughly (just like I did). So now, just relax and make sure you don't do something stupid in your first SAC (just like I did). :P
