Query: Not the best

I was really excited to sell my book back once the course was over for this one. It is a really difficult book to read both to understand and to follow in any continuous sequence (I did pass, though with a decent grade). Several problems are quite confusing, especially in chapter 7 (many students had to see the teacher for clarification). It does give you some HYSYS/Aspen problems to work, which is nice.
