What I found with this subject is that if you understand most of the work it can be one of the most stimulating, thought provoking, and worthwhile subjects you can do.
However what I also found was that to get to the point where you get to feel about economics in the way I just described takes a lot of time, stress and a hell of a lot of hard work.
Unfortunately, I found it's also one of those subjects where if you slacken off a bit, or miss a concept or idea, or don't understand something you can fall way behind and it can affect you in serious ways.
If you stick with it though you should find it worthwhile because aside from the maths involved, it teaches you about the way certain political and financial aspects that dominate our everyday lives work, and that can be a very valuable thing to know.
