Not only is the Go series a great way to develop the communication skills, it’s can also be used to prepare for the national competency test. We recommend Go Movers for grade 6 (level A1) and Go Flyers for grade 8 (level A2), while Go Starters can be used in grade 4 or 5. The series develops the skills that students need to receive good results at the tests and many of the exercises are similar to what they can expect.
