Business Opportunities (old edition)
The best thing about this Business book is that most of the material is actually quite interesting, if somewhat challenging. The worst thing is that the units are quite long, and this means that students only studying 30 minutes a week can take months to get through one unit. With such students lots of the exercises are settable as homework, so it’s not worth getting the workbook. Worth having at least one copy in the teachers’ room to use as a supplement or bear in mind when choosing books.
