The reason there are two versions of the test is that English usage can be different depending on your circumstances. For people who are coming to work or to immigrate, everyday language is more important. As a matter of fact, passing the General Training exam is mandatory for migration to the UK, Canada, Australia, and New Zealand. For academic purposes, you’re going to need to understand more advanced terms and more complex sentences. The Academic version of the test is designed to ensure that you’re ready to begin study, or to receive a professional certificate.
