I have a degree in computer science and I wanted to do another degree in economics.

However, my maths have been weak since high school always scoring slightly above passing rate. During my course of study in computer science I have score 60 marks for my maths module (which covers probability, differential equations, mainly on discrete maths topic).

I would like to revisit my high-school and undergrad maths module to prepare myself.

I have found some free online learning materials at: http://rutherglen.science.mq.edu.au/wchen/ln.html

What are the modules should I revisit to improve on my foundations?

The math in most economics degrees is far, far easier than the math in most computer science degrees. –  Alexander Gruber May 1 '13 at 13:28
    
The amount of maths in econs seems terrifying. I have never taken calculus before as well. gregmankiw.blogspot.sg/2006/06/love-econ-bad-at-math.html –  optimus May 1 '13 at 14:14
    
it does not belong here. –  user45099 May 1 '13 at 15:04
    
I disagree, this is a concrete answerable question about mathematics learning. Questions on this site are not limited to those which apply only to mathematics majors. –  Alexander Gruber May 1 '13 at 20:54

If you are doing an undergrad degree, then you likely will need more applied math classes.

You might see classes like algebra, calculus, finite math, business math, differential equations, linear algebra, probability, statistics, complex variables, real analysis, numerical analysis and the like. You might also be required to take some programming courses.

If you are doing a graduate degree, then you likely need more theoretical classes.

Here you can see courses ranging all the way up to game theory, calculus, differential geometry, differential equations, topology and the like.

If you have a particular school in mind, you should certainly look at their requirements and maybe talk to a counselor.

You should also check out some of the wonderful Opencourseware, for example, at MIT.

Lastly, you certainly want to visit your local universities and look at the course requirements and the books in the library.

Great recommendations! And nice link, too! –  amWhy May 2 '13 at 0:09
    
@amWhy: Thanks, the graduate econ programs are heavy in theory and applied courses and look very tough at the best schools. Also, very expensive!!! –  Amzoti May 2 '13 at 0:10
    
@Amzoti I am pretty weak in maths. I dont know if I should take econs –  optimus May 2 '13 at 15:00

@optimus: I think that we all have weaknesses. The key is how you handle them. If it is really something you want, you should work to build the skills necessary and work hard to that end. Just something for you to think about. Regards –  Amzoti May 2 '13 at 15:19
    
@Amzoti Thanks for your advice. Probably my fear in maths since I failed once in my undergraduate days. –  optimus May 3 '13 at 8:08

I would say the most important are multivariate calc, particularly constrained optimimization, linear algebra, and statistics. I agree with Amzoti that if your goal is grad school, more theoretical work is needed, at least real analysis. There are quite a few "math for economists" books, such as Glaister's Mathematical Methods for Economists. Use the books themselves or to get an idea of the topics needed.
