You have this exactly backasswards. Start with the Becker Beginners. Then the Becker Intermediate book. The Becker Advanced book is a TOTAL WASTE of time. since there are far better readers to be found, mostly for free, on the web. The vocabulary of the Advanced Becker book is not useful. Also, the Advanced Book is far less well done, poor quality of design, etc. The best book is the Becker Beginners. The Intermediate Book is still OK, but still not as well done as the Beginner book. The Intermediate book has a major drawback in that it throws about 50 words ending in JAI, such as PoomJai, etc...and...this is a total FAILURE because nobody can learn 50 of those similar words in one lesson. I have already discussed the phenomenon of INTERFERENCE previously here, and this is why Becker editors made a HUGE BOOBOO, in this case. Still, I highly recommend the Becker books, but not the third advanced book. The dictionary is quite good, and useful on an Android phone.
