I had already described my situation somewhat in another thread, but there seems to be no response to that as yet. So I am hoping to attract the attention of some veterans in this new thread, like Econ, gstergia to help me get out of the mess I am in.

First of all, I am a a 4h-year student of a Bachelors Program in Business Administration, otherwise known as BBA. You may call it the younger brother of the much known MBA. Unfortunately, I lost interest in the field of business not long after joining the program and I dream about being an economist day and night. Having realized my mistake, I now plan to do my Masters in Economics and then try for a PhD. But the problems start here:

1) My BBA program included the following relevant courses that somewhat relates to Economics:

Mathematics for Decision-Making - some calculus related to differentiation, integration, limits, continuity, a little bit of algebra, mean value theorem etc all of which I have mostly forgotten since I took it in my first semester and its been more than 3 years since. Furthermore, I got a C+ because the teacher was not good.

Micro-economics - you know what this includes and I don't need to elaborate on this. I got an A.

Macro-economics - though my grade is not out as yet, I am more or less expecting an A.

Statistics 1 - covered descriptive statistics and probability and I got a B+

Statistics 2 - correlation, regression, hypothesis testing etc and B+

So you can see that my main weakness is in Maths. In fact, given the profile of some other people I have come across in the threads, my maths background is pathetic

2) The place that I am in, Institute of Business Administration (IBA), is the business school of University of Dhaka (Dhaka is the capital of Bangladesh, which is just beside India). Now, University of Dhaka is the best uni. in my country and people would kill to get into IBA. In fact, I had to compete with 3500 students for a place in a class of 70 (15 have dropped out after getting in). But the problem with the uni. is the extreme rigidity as I am simply not allowed to take any course outside my department. Thus, since IBA itself does not offer any maths course others than the one I just mentioned, I cannot take the necessary maths courses without which universities are unwilling to take me for the MSc Econ program.

3) Neither do we have Maths summer camps or something similar in our university or any other uni. in our country. I am basically stuck

So, the question is, what do I do?

I have some other questions which are not exactly related to maths but which are just as important but I hope to get some input from you guys on this first. So, please please help. Help me get out of my depression.
