The language in this book is everyday Hungarian - within the first few chapters, you have basic introductions, eating out, directions and shopping, all the really essential stuff - you won't starve on holiday with this book.
Useful (and interesting) sections on Hungarian culture, customs and manners. Invaluable.
The grammar is fairly well explained, although I have seen better.
No listening comprehensions. Reading comprehensions far too easy.
Grammar points explained one after the other, sonetimes as many as 10 in a chapter, with inadequate practice tasks.
Vocabulary thrown at the learner with little in the way of practice. To learn the vocabulary effectively, the student needs to devise his or her own activities, such as flashcards or memory games.
This isn't a bad language learning book, but it could be improved by adding a workbook for grammar and vocabulary practice. With little in the way of competition, TY Hungarian should be the first port of call for any learner of Hungarian. However, if you can afford it, Hallo, Itt Magyaroszag! by Erdos and Prileszky, used in conjunction with Hungarian Verbs and Essentials of Grammar by Torkenczy would be a much better option.
