For iPhone, iPad, … iGE Lite is free … the complete iGE on sale for $6.99
iGE is written by a team of linguists at University College London (UCL), independently ranked as one of the world’s best Universities. The grammar you’ll be learning is based on recent research and best practice in the field.
The iGE course covers the same ground as a first year undergraduate course in Modern English Grammar. But that does not mean it is difficult to follow! We have written iGE to be accessible, with clear explanations, colourful notation and lots of examples.
