First year - introduction to concepts and general principles - graphics diagrams. Pretty rosey images of neo-classical economics. University generally makes you do one unit along the lines of 'introduction to econometrics'.
Second year - the mechanics behind these principles (intermediate micro & macro) - basically you deal with the maths behind the graphs - derivatives galore. You usually do 'intermediate econometrics' to ensure you get the maths, start doing a lot of regression analysis and diagnostics.
Third year - policy implications and issues (advance micro and macro), more realistic portrayals of the economy. 'Advance econometrics' is usually optional, but it extends upon regression analysis, you get to learn pompous stuff like 'maximum likelihood estimator', 'probit models', '2SLS & endogeniety' etc... Basically, by this stage, you can go through any economic journals and understand every inch of it.
Of course, you also get to do more interesting stuff then studying how the economy ticks, there's usually electives which deals with normative aspects of economics, stuff like the political economy or history of economic thought.
