I loved ECON1002 much better than ECON1001, because it had so much more relevance to today's economy than ECON1001, not to mention the lecturers are far superior than ECON1001. There is slightly less maths compared to ECON1001, but nonetheless you do need to know calculations. Learning the concepts is perhaps more difficult than in ECON1001, but usually the questions they ask aren't very hard.
