The book perfectly targets the "Intermediate" (B1-B2) level. This is the critical stage where learners know the basics but struggle with complex structures and exceptions. It bridges the gap between "textbook English" and "real-world English."
However, if the cost is the barrier, there are safer and more ethical alternatives than resorting to a "Cambridge English Grammar In Use torrent."
This is a controversial topic. Some argue that if a student genuinely cannot afford the book and has no library access, downloading a torrent is a moral grey area. Others point out that Cambridge University Press is a non-profit academic publisher (its profits go back into research and education), and every illegal download potentially raises prices for paying customers.
